M13 Release Notes

READ THIS Before You Install

Using AOL 4.0 or earlier and running a Mozilla build simultaneously may cause problems. No problems have been reported running AOL 5.0 and Mozilla.

If you experience a crash upon launch, delete your Mozilla registry. The format of the Mozilla registry has changed on all platforms since M9.

Mac OS: Open your System Folder's Preferences folder, and delete the "Mozilla Registry" file.
Windows: Open your Windows directory, and delete "mozregistry.dat".
Linux: open your ~/.mozilla directory, and delete the "registry" file.

For more information, please see news://news.mozilla.org/37E8A320.D3420962%40netscape.com. If you are installing on Win32 also read the installation instructions for additional information on problems with crashing upon launch.

The feature that remembers passwords has problems (Mac OS only). It is recommended that you click Cancel when you are first asked if you want this feature turned on. You can also turn off the feature in Edit:Preferences:Advanced by unchecking the Automatically Prefill Usernames and Passwords checkbox. (See bug # 21596.)

Install into a clean directory, or delete previous builds before installing. Installing on top of previous milestone builds or released product builds may cause problems. Incompatibilities may be introduced from milestone to milestone while the software is under development.

On Linux systems that use glibc 2.0 (such as RedHat 5.2), there are problems with dl functions (dlopen(), dlsym()) not being thread safe. This might cause your M13 build to randomly crash at startup. If this happens to you, try running the application a few more times. The bits posted on ftp.mozilla.org are built on RedHat 6.0, which uses glibc 2.1 and does not have this problem. For more details, see bug 8849.

Do not use Java Plugin 1.3. It doesn't work with the most recent Mozilla builds, and crashes will result. Make sure there are no files named *npjava*.* in either the bin/plugins directory or the NS4.x plugins directory. This problem is being addressed. For more information about this bug, see bug 5369.

Proxies ARE working in this release. See bug 8559 for details on setting up.

Installing the M13 Release Build

Installation Instructions -- Unix

Create a directory named "mozilla" and move the tar.gz file into the mozilla directory.

mkdir mozilla ;
mv mozilla*.tar.gz mozilla

Change to the mozilla directory and untar the archive. This will create a directory called "package".

cd mozilla ;
gzip -dc mozilla-i686-pc-linux-gnu-M13.tar.gz | tar -xvf -

Change to the "package" directory.

mv mozilla*.tar.gz ../ ;
cd package

Run mozilla with the run script:

./mozilla

Important: If you are running Seamonkey on Solaris see also the Mozilla on Solaris FAQ, which documents Solaris 2.6 patches needed to build and run.

Mail Instructions for Unix

You can migrate an existing 4.x profile, or create a new profile and use Account Setup to set up your servers.

Installation Instructions -- Win32

You will need a copy of WinZip. This is shareware available at http://www.winzip.com (also at http://www.download.com).

Important: You must run the Seamonkey installer (mozilla-win32-installer-M13.exe; find it here) at least once when installing M13. The installer updates two Microsoft C Runtime Libraries that the zip file cannot change: MSVCRT.DLL and MSVCIRT.DLL, which must both be version 6.0.8168.0 or later. These updated DLLs are necessary to prevent a crash on launch of Seamonkey. Note: The installer requires a reboot when it updates these DLLs.

Click once on the mozilla-win32.zip link. The file will be downloaded to your default folder.

Click on the mozilla-win32.zip file to launch WinZip.

After clicking "I Agree" to terms of WinZip shareware, click the Extract button in the WinZip tool bar. An x86 folder with application and associated files will be unzipped.

Select Mozilla from x86 folder to launch the program.

Run "mozilla.exe" to use browser and mail.

Run "viewer.exe" to run only the gecko layout engine

Note: If you have an existing 5.0 profile as well as unmigrated 4.x profiles, and the command mozilla does not launch seamonkey, use the command mozilla -installer which brings up Profile Manager and allows the user to select a profile.

Mail Instructions for Win32

You can migrate an existing 4.x profile, or create a new profile and use Account Setup to set up your servers.

Installation Instructions -- Mac OS

If you have StuffIt Expander™ installed and your browser is configured to use it:

Click once on the mozilla-mac.sea.bin link. The file will be downloaded to your default folder (usually the desktop) and StuffIt™ will start up and convert it to mozilla-mac.sea for you. Then StuffIt will open up mozilla-mac.sea and convert it to a folder called mozilla-mac for you.

Open the mozilla-mac folder and double-click the file "mozilla." (Note: you no longer need the .bin or .sea files.)

Note: If you try step one and your browser asks you what you want to do it's because you don't have StuffIt™ configured. In that case, just click Save and continue from Step #3 below.

If you do not have StuffIt Expander™ installed or your browser is not properly configured:

Make sure you have StuffIt™ somewhere on your hard drive.

Click and hold the mozilla-mac.sea.bin link.

Choose "Save this link as...".

You will see a file dialog box where you can select where you want to save the file (for example, your Desktop).

Note: Do not use a slash (/) anywhere in the access path for the Mac installer. Spaces are okay, but avoid other special characters.

Click the Save button.

Double-click on the newly created icon "mozilla-mac.sea.bin".

StuffIt™ will start up and simultaneously create a file "mozilla-mac.sea", and a folder called "mozilla-mac."

Open the mozilla-mac folder and double-click the file "mozilla." (Note: you no longer need the .bin or .sea files.)

Mail Instructions for Macintosh

You can migrate an existing 4.x profile, or create a new profile and use Account Setup to set up your servers.

Uninstalling the M13 Release Build

Linux

Remove the /package directory where you installed Seamonkey

Remove the ~/.mozilla directory, which contains profile information

Windows

Delete the directory where you installed Seamonkey

Delete c:\windows\mozregistry.dat

Delete the user profile directory, \users50

Mac OS

Remove the the folder Mozilla in the Documents folder

Remove the file "Mozilla Registry" in the System Folder | Preferences folder

Remove the folder where you installed Seamonkey (probably mozilla-mac-M13)

*Note:"cookperm.txt" ("cookperm" on Unix) is a file used to selectively accept cookies from certain sites and not from others. It is used only if you set your preferences so you see a warning before accepting cookies. To do that, hand edit the prefs.js file to include:

user.pref ("network.cookie.rememberAboutCookies", true);

Limited Support Features

Caching

You can turn on caching in Preferences:

Open Preferences.
Click Debug:Enable Memory Cache.

Turning on caching should boost performance over dialup connections (LAN users, however, won't see huge speed improvements).

Support is enabled for memory caching only, not for the disk cache, so cached data won't be remembered across sessions. Please DO NOT report this as a bug.

Several cache bugs are being addressed:

Sometimes the throbber will not shut off. (bug 21162)
You can't clear the cache, change its size, or change how oftren data is validated with the server. (bug 20893)
Reload and Shift-Reload actions will not alter the behavior of the cache (bug 21137)

Available Navigator Functionality

Functionality	Description	Comments

Toolbars	Toolbars display above and below content window, most buttons working though a couple are not hooked up to execute a command.
Downloadable chrome	You can dynamically change the chrome (apply new skins and new content) in M13 with the following caveats: (1) Only Navigator is using the new chrome URLs. Messenger hasn't made the switchover yet. (2) Changes aren't persistent yet, so if you change the skin, the change won't be remembered. (3) The window doesn't dynamically refresh (once the window manager is further along, it will). In order to see your changes, you need to open up a new window after running the script to set the new skin.	See the sample code in section 9 of the downloadable chrome spec

Cancel news message	If you are the author of an article, then the delete button (or the Edit \| Delete Message menu item) cancels the article. As with 4.x, you can only cancel one article at a time. Due to several dialog / alert bugs, you won't see the confirmation dialog ("are you sure you want to do this?") or the alert open cancellation. ("message cancelled."). For now, On Windows and UNIX, look for these messages in the console window.
Address Book	The Personal Address Book is displayed in the left pane. LDAP and additional address books are not working yet.

Additional Mail Functionality

The multiple POP accounts feature is available for you to try out. To set up multiple POP accounts, open the mail application and use the Account wizard. You will need to have identity and server information for the second account.
For POP3, the "Leave Messages on Server" option is turned off by default. This means that messages are deleted from the server when you download them to a local mail folder. If you wish to keep messages on the server, either use Edit:Accounts Setup:POP3 Server and select "Leave Messages On Server, or switch to IMAP.
You can use the Address Book window and the Select Address dialog. The Personal Address Book is working for adding cards, editing cards, and deleting cards. LDAP and additional address books are not working yet. The data is stored in a file called "abook.mab".

Known Issues

Browser and General Issues

Important plea regarding filing new bug reports: Many duplicate bug reports are being filed about issues with TAB, ALT, CTRL, or arrow keys not working properly. These are nearly always duplicates of bug 9701, "nsWebShell Key events not working until focus set in window (TAB, PgDn, ALT+, CTRL+)" (M14, P1, beta1). Before you file a bug on this subject, please check this bug and make sure you are not filing another duplicate.

If you hide the navigation toolbar, a crash will occur when you reselect the navigation toolbar from the Toolbars submenu (View menu). (bug 22301)

The Search menu dialogs (for instance, Search:Search the Internet) are intermittently unstable and can cause crashes. (bug 23493)

Mac OS only: In the Appearances:Themes preferences window, clicking on the site link in the "Selected Theme" box causes a crash. (bug 22970)

Clicking the Back or Forward buttons while pages are loading may cause the browser to quit. (bug 17932)

(Linux only) In 256 colors, loading the test10.html document in Mozilla will cause a crash. (bug 11090)

Loading problems (possible crash or freeze) sometimes occur on pages that contain applets.

Linux only: The OK and Cancel buttons in the Wallet Contents dialog don't work. Click the close box to close the dialog. (bug 25039)

Copying text from the browser window frequently won't work. (bug 21832)

Mousewheel scrolling

Unix: You must have your X server properly configured. For XFree86, add a line to the Pointer section of your XF86Config files such as "ZAxisMapping 4 5". Also be sure that the Protocol line is set up correctly for your mouse.

Windows: If you are using a Logitech wheel mouse, scrolling with the wheel in Mozilla may not work while Logitech's em_exec program is running. A workaround for the problem (which may involve upgrading your mouse driver) is documented in bug 20618.

Mac OS: Mousewheel scrolling (for USB mice) is not yet implemented for Mac OS.

The Back button menu does not always list previously visited URLs. (bug 17430)

You can't connect to all secure sites (URLs beginning with "https://") in the M13 release.

The Stop button fails intermittently

Keyboard shortcuts/command keys are not available for most menu items with the exception of the following for the mail compose and editor window: Ctrl-C (copy), Ctrl-V (paste), Ctrl-Z (undo). and Ctrl-Y(redo) and their Mac OS equivalents. The old Unix equivalents (using Alt- instead of Ctrl-) don't work; use Ctrl- .

Within Viewer, many options within the Debug & Tools menu items are not currently working or produce unpredictable results.

Printing

Printing pull-down menus crashes the browser. (bug 22012)

Frames print on different pages. (bug 7201)

Mac OS and Linux: Pages print with large fonts; text is cut off. (bug 24405)

The password field prints blank. (bug 24406)

The button in the combobox does not print correctly. (bug 24367)

Plugins

After installation, mozilla creates an empty "plugins" folder. Manually delete this empty folder so mozilla can search for existing plugins under any 4.x installation on your machine and play the plugin. If you don't do this, a blank window will appear. Another workaround for this is to copy the .dll files (windows) or create a plugin alias (Mac OS) or copy the .so files (Linux) and manually place them in the empty "plugins" folder under mozilla installation.

Some file types (.mov, .au) are not understood by mozilla. You cannot add a new mime type to launch a helper application. (bugs 20407 and 18656.)

Linux: The Flash plugin does not work. (bug 18897)

Mac OS: Quicktime does not work. (bug 24718)

Bookmarks and History

Incorrect bookmark behavior can be related to profile problems. See Issues With Profiles.

Drag and drop is not yet implemented, but you can use cut, copy, and paste to manipulate your bookmarks.

Sidebar

To hide the Sidebar, select Sidebar from the View menu. Hiding the Sidebar works only for the current window -- new windows will open with the Sidebar showing. (bug 16516)

Mac Os only: You can't add or delete panels in the Sidebar. (bug 22248)

Profiles

IMPORTANT: All the information regarding profiles is stored in the registry file. The registry file gets created even if you have used earlier versions of Mozilla (Apprunner). When you check out a new build, make sure you delete or rename the following items before you install, build, and run the new executable:

Windows mozregistry.dat ( c:\winnt or c:\windows or equivalent),
Mac OS Mozilla Registry (System Folder:Preferences),
Linux registry (~/.mozilla/)

To create a new profile name with a space in it, enclose the name in quotation marks (for instance, "My Profile").

You open Profile Manager with the command line argument : -ProfileManager. The Profile Manager user interface appears, supporting creating a new profile, and deleting and renaming existing profiles. When you finish any of the tasks you can click Exit to quit the Profile Manager. You can click a Start Communicator button to start Mozilla with a selected profile. Also, users can migrate 4.5 Communicator profiles (Windows only, for now).

Various command line options to create and manage profiles are:

# mozilla -P <Profilename>

Runs Mozilla with the <Profilename>.

# mozilla -CreateProfile "<Profilename> <ProfileDir>"

Creates a profile (i.e., <Profilename>) and creates a directory at the specified location i.e., <Profiledir> and launches Mozilla.

# mozilla -CreateProfile <Profilename>

Creates a profile and creates a profile directory under default profile location.

# mozilla -ProfileWizard

Launches the Create Profile Wizard to create a new profile. The Create Profile Wizard lets users create a new profile at the default location or the location of their choice. At the end of the process a profile is created and marked as the current profile, and Mozilla is launched with that profile. The wizard is currently just two screens. Mail and News related preferences/information will be collected by a different application.

# mozilla -ProfileManager

Brings up Profile Manager for managing profiles. Users can select a profile and click on the Start Communicator button to launch Mozilla with the chosen profile. The current profile (usually the last used profile) appears preselected.

# mozilla

Several scenarios:
number of profiles = 0 --> Brings up Create Profile Wizard
number of profiles = 1 --> Launches Mozilla directly with that profile
number of profiles > 1 --> Brings up Profile Manager
Default profile locations for profile directories are <3 levels up from the exe location>\Users50, on Windows :Documents:Mozilla:Users50: on Mac OS, and ~/.mozilla on Linux.

Profile Manager (Windows and Linux only): The Rename and Delete buttons are not working properly.

Profile Migration (on Windows only): 4.5 profiles now can be migrated to 5.0. In the process of migration, 4.5 profile information is undisturbed. In 5.0 the new location for the migrated profiles is the default location as mentioned in the above paragraph. Migration is functional on Windows only, but will soon be extended to the Mac OS. (A date for Linux availability is currently unknown.)

To migrate 4.5 profiles, run Mozilla with the command line option -installer. The profile to be migrated is listed as <profilename> - migrate in the Profile Manager's list box. Users can select a profile to be migrated and click on the Migrate button. If the migration is done successfully, the suffix ' - migrate' disappears in the display, marking that profile as a 5.0 profile. Currently, only the prefs.js file and mail and news folders are copied in the migration process. Users cannot rename or start Communicator with a profile that must be migrated. With the changes that went in at the end of M7, it is required to create a 5.0 profile before using the migration service. This will be fixed in M8 (so that there is no dependency on having a 5.0 profile).

If the Bookmarks menu has only the Add Current Page and Manage Bookmarks menu items, and they are not followed by a list of bookmarks, then bookmarking will not work correctly until you do one of the following:

Migrate an old 4.x profile over to Seamonkey, or

Create a new profile by following these steps:

Remove your current profiles and mozregistry.

For Windows, remove the "mozregistry.dat" file in your Windows (or winnt) directory; also remove the entire "Users50" directory.

For Mac OS, remove the "Mozilla Registry" file from your Preferences folder (System Folder|Preferences|Mozilla Registry). Then remove the "Users50" folder from the Documents folder that was placed on your hard drive when you installed Seamonkey (documents|mozilla|Users50).

For Linux, remove the .mozilla/ directory.

Launch Seamonkey and create your new profile. The menus should now appear and behave normally.

Editor

The Color Picker doesn't work. (bug 23739)

Menu and toolbar items are not dimmed when they should be. (bug 5563)

Loading a remote stylesheet fails, and can cause the editor to crash. (bug 11859)

The font increase and decrease buttons are not working. (bug 18774)

A number of keyboard accelerators may not work, particularly those contained in the File menu. (bug 13378)

The editor doesn't launch on the Mac OS unless you give the browser the focus. (bug 9701)

Mozilla crashes on launch at times. (bug 8849)

Preview is not working. (bug 9200)

The image dialog is not fully implemented. (bugs 9751, 9753, 9754, and 9755)

The menu and toolbar items don't get disabled. (bug 5563)

There are some missing menu items. (bug 14342)

You must click in a document in order for the caret to reappear.

9701

Mac OS and Linux: The spellcheck dialog does not come up. (bug 6864)

Mac OS only: The editor doesn't launch. (bug 9701)

Mac OS only: Toolbar buttons do not appear until mouseover. (bug 13438)

Linux (Solaris) only: Highlighting doesn't work. (bug 10699)

Linux only: Mozilla may crash on launch. (bug 8849)

Linux (Solaris) only: Highlighting doesn't work. (bug 10699)

Java

If you have installed the latest JRE 1.2 from Sun Microsystems, you may crash at startup if the Java plugin is present. To fix this, remove the following dlls from the Plugins folder located in your 4.5 (or later) Communicator directory: npjava32.dll, npjava12.dll and npjava11.dll.

On Linux, Java is not yet implemented.

Javascript

document.write fails to write HTML tags and any text written before the last tag. (bug 11141)

JavaScript alert dialogs are not being displayed. (bug 4279)

None of the JavaScript window.xxx() functions work with Mozilla windows. Windows can be opened using the ToolkitCore, but those windows don't play well with most of the JavaScript properties and methods.

Small Fonts on Linux

If the fonts are too small in your environment, it may be possible to alleviate this by setting a preference in Mozilla. Add a line like the following to the preferences file (~/.mozilla/Personal/prefs.js):

user_pref("browser.screen_resolution", 120);

This sets the dpi to 120. If you set the pref to zero (0), Mozilla will use the X server's dpi value. If the pref is not set, it uses the default value of 96.

There is some info about setting the X server's DPI value at http://www.mozilla.org/unix/dpi.html.

If your fonts are still too small (or too large) after setting the DPI correctly, you can adjust the font size as follows:

setenv GECKO_FONT_SIZE_FACTOR 1.5

Note that the latter only affects fonts. The screen_resolution preference affects anything that specifies absolute size (e.g. CSS "pt" points).

Mail and News

An error message appears after you send mail or save as draft or template using Cyrus IMAP. (bug 24715)

POP: Selecting multiple messages (shift-click) to delete may cause a crash. (bug 24747)

Using a mailto link (or clicking on an address header) in the mail window causes duplications in the message list, and causes the list of mail and news servers and folders to sort in reverse order. Exiting corrects the display. A crash may occur on exit. (bug 23782)

Collected addresses are not added to the address book. (bug 23362)

if you create a new profile, create a New account, then go to Mail, there appears to be no "Collected Addresses" address book. Selecting names in your mail account inbox also doesn't create the book. Workaround: quit and re-open to see the Collected Addresses book. (bug 18476)

The twisty cursor isn't properly updated when folders are added or removed. (bug 10208)

The biff (new messages) icon does not return to normal state ofter new messages are read. (bug 23058)

Messages sent using the Send Later option are retrieved marked as READ (in POP accounts). (bug 17943)

The toolbar color selector for composing HTML messages doesn't work. (bug 23739)

In the thread pane, if you right click to view the context menu you see a flash under the File menu. (bug 21223)

IMAP mail filters cannot move messages to local folders or folders on other IMAP servers. If you've migrated your filters from 4.x, the filters that perform this action will not work in 5.0. This feature will work in a future release. (bug 17174)

Selecting a local empty folder does not refresh the thread pane. (bug 21772)

In the thread pane, you cannot use shift-click to extend the selection to include a message immediately above the currently selected message. You can extend the selection if you click a message that is 2 or more away from the currently selected message. Workaround: use CTRL-Click. (bug 21972)

Account setup issues:
- Crashes sometimes occur while using the account setup dialog, particularly when you add multiple accounts during the same session. (bugs 25036 and 25095)
- Be sure to fill in the incoming server field when setting up a new account. Otherwise, a crash may occur when you finish the account setup dialog. (bug 18075)
- Linux and Mac OS only: When you create an account using the account setup dialog, if you can't use the mouse to select a server, use the Up and Down arrows instead.
Printing mail only prints the message body, not the headers. (bug 12505)

Cancelling a news message doesn't remove it from thread pane. (bug 8216)

"Send Later" fails when there is no local mail folder hierarchy. (bug 18260)

Although you can bring up the Search and Filters dialogs, backend code for these features has not been implemented so you will not be able to perform any functions in these dialogs.

If you have local folders with more than 1,000 messages, don't point the Mail application at your actual local folder hierarchy. Larger folders may take too long to load and may consume vast amounts of memory.

Mac OS only:

Problem with creating subfolders: You may not be able to create more than two layers of subfolders. Workaround: Instead of selecting a parent folder and then choosing New:Folder from the File menu, choose New:Folder first, then select a parent folder within the dialog. (bug 24942)

If you add a card to the address book, and then compose a message, the new card is not used for autocompleting the recipient field. Workaround: Close and re-open the application. (bug 18629)

After startup, you must click inside the browser window to bring it to the front before using any of the menus. (bug 9701)

Linux only:

Text under the toolbar buttons is not readable. For a workaround, see http://www.mozilla.org/unix/dpi.html.

Issues in the Mail Compose window:

If you use keyboard shortcuts, the correct function is performed but a text character corresponding to the selected shortcut (for instance, "m" for "Show Message") is also inserted into the message. (bug 24072)

When you choose plain text reply, too much space is inserted above the quoted text. (bug 24375)

The cursor does not appear in the message field until you begin typing.

The received message does not wrap lines, so you may want to embed hard returns in your messages.

Messages may contain either too much vertical white space or not enough.

If you are using plain text (instead of HTML) for messages, you may need to press Enter twice at the end of a line to move the cursor to the next line.

Preferences/Installer:

The Mac installer for the M13 binary could be very slow compared to Windows and Unix builds -- please be patient.
There is very little need to directly edit Preferences file, prefs.js. Both profile migration and new profile creation are very easy to accomplish with the improved Profile Manager. Users who have had trouble setting up Mail server(s) before should try Edit | Account Setup menu available in the Messenger window.
Mozilla can migrate Communicator 4.x profiles you have on your system. Choose an existing one made by 4.x from the list and a new one will be created for Mozilla.

The window for profile migration will appear the first time you start a new Mozilla build after the installation.
If it does not, you can start with the profile manager: mozilla -installer (Unix & Win). Mac users can start with the Mozilla Profile Manager file.

If you have used an earlier version of Mozilla, we recommend that you delete the file called mozregistry.dat (Win)/Mozilla registry (Mac)/registry (Unix) before you run M13 Mozilla. (Don't delete Netscape Registryfile for Mac, which is for Communicator 4.x.). We recommend this procedure because during an earlier Milestone, i.e. M10, there has been a change in the way registry works and the old registry prior to M9 will not work well with builds later than M9. Read the section in the Release Notes called Files Used or Created to find out where you can find these files.
When you start M13 after having deleted mozregistry.dat or registry, you will be asked to create a new profile. If you name an existing profile, that profile will be used. Otherwise "Default" profile called "mozProfile" will be created. If this latter happens, you can replace the prefs.js file in the Default folder with the one from an existing profile directory. (Note that the default profile name changed from prefs50.js (of M8 and earlier) to prefs.js starting with M9.)
Note on non-ASCII path names: For both Profile manager and Mail/News Account setup manager, it would be best to avoid choosing folder or path names which contain non-ASCII characters at this point. Internationalization of these is not complete yet. (Mail/News Account names in non-ASCII display OK, however.)
Also read the Installation instructions for your platform carefully in this Release Notes.

Browser:

Performance: Generally speaking, M13 should be quite usable as as a daily browser for international users. Note some of the bugs described in this section, however.
Copy/Paste: Copy/Paste operation of non-ASCII data is working more or less well in M13 within Mozilla with the exception of Mac which currently has a problem of copying from the Browser window. See below in the Editor section for details.
Window Title display of non-ASCII: Due to a dependency on platform specific widgets, currently Mozilla cannot display Window titles (Browser, Editor, Messenger, etc.) if they contain non-ASCII characters not supported by the operating system. For example, Korean titles will display OK under Korean OSs but not under Japanese Windows, etc.
Sidebar: You should be able to display non-ASCII names here, e.g. Related sites. Sometimes display of non-ASCII names may be corrupt. There are a few bugs on this problem. See Bugs 24557, 24933.
Bookmarks: Bookmarks titles support non-ASCII characters. (Note: IE favorites are not imported correctly yet and will not display non-ASCII characters well. See Bug 6770.)
Accept-Language: Backend work for Accept-Language was completed in M13. The Pref UI is not done yet but Mozilla now sends out Accept-Language values in an HHTP header when the following line exists in prefs.js: e.g. user_pref("intl.accept_languages", "ja,en"); . The language values (ja and en in the formula) should be from ISO-639-1.
Font Preferences: Backend work for font preferences was completed back in M12. The UI for font preferences now also exists in M13. Changing fonts through the pref UI does not work yet, however -- we expect this work to be completed in M14. In the meantime, font names and sizes can be manipulated by editing prefs.js file for all platforms -- in M12, this worked only for Windows. Here are some highlights of new font preferences at M13. Font work is not finished yet and some of these specs might change later.

The font preferences can now be set for 5 generic font families: serif, sans-serif, monospace, cursive and fantasy

Mozilla does not map non-generic font family names such as "Times", "Courier", and "Arial" to corresponding CJK fonts. Web page designers should use generic font names if this is the desired result.

The font preferences are in principle set for language/script groups (except for Unicode) rather than for charsets as was done in Communicator 4.x.
The font size can be set for: variable or fixed.

variable setting only controls the default HTML display which is set by the following line:

user_pref("font.default", "sans-serif"); -- serif should be the default and this probably does not have to be set unless you want to change the HTML display default to sans-serif type. The 2 values most often used for this HTML display default would be serif or sans-serif.

fixed setting only affects monospace font setting. e.g. mail message viewing.
The font sizes are measured in pixels rather than in points.

These preferences will be consulted to select fonts to use in case the page you are visiting does not have fonts specified.
Non-ASCII font names are also supported. We don't have the UI working yet for setting fonts but you can play with non-ASCII font names and font sizes by editing prefs.js. Be careful, however, because prefs.js must be in UTF-8 if it contains any non-ASCII characters. UTF-8 editor is hard to find. Japanese font names are known to work on Japanese Windows95/98/NT4 and on Macintosh. Font names to use are the same ones found in Control Panel | Fonts for Windows, Key Caps utility for Mac, and the font family name for Unix as indicated by the red bold type in this example. Font names can also contain spaces.:

-adobe-courier-medium-o-normal-0-0-75-m-0-iso8859-1

Help us by trying out the Korean and Chinese font names under the respective language operating systems. Below is an illustration on how you might edit prefs.js for font preferences on Japanese Windows. The key point is that if prefs.js contains non-ASCII characters, it must be encoded in UTF-8.:

Find your current prefs.js file, and make a backup copy, then rename the original prefs.js to something like jpprefs.txt.
Using a text editor like NotePad, edit jpprefs.txt with the following templates for font names and sizes:

user_pref("font.name.serif.ja", "Font_name_in_JPN"); -- You can set fonts for each of the 5 font types mentioned below.
user_pref("font.size.variable.ja", 12); -- sizes are in pixels. This controls HTML default display.
user_pref("font.size.fixed.ja", 12); -- sizes are in pixels. This controls monospace display such as <pre>.. </pre> text or Plain Text Mail message display.

Possible font types: serif, sans-serif, monospace, cursive and fantasy.
Possible language groups are: ja, zh-TW, ko, zh-CN, x-western, x-central-euro, x-cyrillic, el, tr, x-unicode, zh-TW
Possible font size categories: variable, fixed.
Possible font size: integer in pixels.

For mail message viewing, due to Bug 26182, the font types and sizes are currently controlled by x-unicode setting only rather than based on the language of the message in view. For example,

user_pref("font.name.serif.x-unicode", "Font_name_in_JPN"); --> for HTML message display
user_pref("font.name.monospace.x-unicode", "Font_name_in_JPN"); --> for Plain Text message display

When inserting font names in Japanese, pay special attention to how the font names are spelled -- is the alphabet part using full-width Roman? Is the space half-width or full-width? You can see how the font names are written by looking in the Windows Control Panel's Font utility program.
You can also set the screen resolution with the following type of preference item in prefs.js file.

user_pref("browser.screen_resolution", 120);

Now that you have edited jpprefs.txt using Japanese font names, you should convert the encoding to UTF-8 using the following command line utility shipped with Mozilla (Win and Unix only) in the same directory as the mozilla executable. See below on details of how to use the conversion utility.

nsconv -f Shift_JIS -t UTF-8 jpprefs.txt prefs.js

Note: nsconv does not replace an existing file of the same name -- that's why you should rename the original prefs.js to something else first.

Now Mozilla can read the Japanese font names you specified and reflect your choice.

Any additional Japanese editing should be done on jpprefs.txt only. Then the conversion utility should be used to get the UTF-8 version of it -- unless you have an editor which can handle UTF-8 data directly. Note: On Windows 2000 (currently Beta), editing utilities should be able to save data into UTF-8. If you know of other such editors, please write to me and tell me about it.
None of these hand-editing would be needed when the font UI is done, which should be coming in M14.
Unix font display problem and future directions:

Currently the code bases the "line height" always on the Latin 1 font height. Since other language fonts (e.g. Japanese) could be larger than the Latin-1 fonts on Unix, lines look too close together and even overlap in some cases. These effects are visible in both UI and HTML display. In the near future, we will be making a change in such a way as to base the line height based on the language of the text being displayed. This means that the line height needs to grow when dealing with Japanese texts, for example. This should improve the situation considerably.

Big 5 fonts on Unix:

It is now possible to use Big5 fonts with the suffix big5.et-0.
Fixed!: Big 5 fonts and Japanese Kana display on Unix: In M12, when you have Big5 fonts like Taipei on your Unix system, due to a Big5 converter table error, it led to non-display of Japanese Kana characters. This Bug 21209 was fixed in M13.

Form: Form submission of non-ASCII data is working generally.

Fixed!: Multipart file upload is now working in M13 --> Bug 8209.
Fixed!: If a web page form uses JavaScript and escape() function on form input data, at M12 JS returned unicode data instead of the charset which matches the web page. This led to incorrect data submission and failure of search. Bug 22594.
There is a bug which shows only blank for non-ASCII data input when the Back button is pressed on the page which resulted by submitting form data. Cf. Bug 22580.

GFX widget/Ender is ON by default. This means that all input areas in M13 support non-ASCII character input including input using CJK IMEs. Read the Editor section below for more information.

M13 converter(s): There are no new converters in M13. See here for a list of all the converters at M13.

Unix charset testing: As mentioned in the M7 Release Notes, the display for the supported charsets except Armenian, Thai, and Vietnamese should be working. We would like users to continue to look at various Unix charsets and file a bug if a problem is found. The list of the supported charsets at M13 can be found below. Please download the Unix binary and check out our support for these character sets. (Note: You need appropriate fonts to display these languages -- pcf.gz format on Linux. Visit this site for ISO and Cyrillic BDF fonts, and this site for multi-byte language fonts. If you want to get the entire international font set, try one directory above for this file, intlfonts-1.2.tar.gz . For converting from BDF to PCF format fonts, use bdftopcf utility. Once installed you need to update the fontsdir, i.e. mkfontdir, and then rehash the font path, i.e. xset +fp `pwd` .)

View | Character Set menu:

Note: The current Character Set menus (including the name of the menu itself) are temporary and will be replaced in M14 by a new single dynamic menu. The new menu specs for the Browser have been published here. The name "Character Set" will also be replaced by "Character Coding". At M13, much work has been completed -- according to the specs above -- to make the Character Coding menu dynamic, customizable, and eventually accommodate new Character sets via a plug-in directory. The dynamic Character Coding menu will use the Extensibility Model as discussed in this document.
You will notice that there are 7 Character Set Menus in the Browser window, and 6 in Composer/Editor and Messenger.
The first 6 "static" menus with sub-titles such as "ISO" constitute a temporary workaround for long, non-customizable and non-scrollable menu.
The 7th Character Set menu -- found only in the Browser window -- is the dynamic menu which is under development but will replace the workaround menu in M14. This is the same menu as the first 6 put together. It does not scroll under Linux and Windows and so you cannot probably see the whole list except on Mac, but the dynamic menu is created via a script and it will be customizable.
Both types of menus should work in M13 and one of them is actually redundant. This is harmless, however. Character set menus in other components are still static at this point and you will not see the dynamic menu.

View | Character Set menu usage:

You can switch to different Character set upon encountering a page which does not have a meta charset tag and which is not displaying correctly. If you happen to have a charset detector ON and if the display is failing, you need to first turn OFF the detector setting, and then try the Character Set menu. Otherwise, the charset detector's choice will always predominate over the manual menu selection. You will not see a checkmark next to the menu item yet, however.

Charset detection modules in the Browser Menu.

The charset detection modules for Chinese, Japanese, Korean, East Asian (CJK), Chinese (Simplified & Traditional Chinese), Ukrainian, and Russian are in a menu below the Character Set menu.

Russian & Ukrainian: Crashing bugs reported for Russian and Ukrainian auto-detection have been fixed in M13. Cf. Bugs 17094 & 17103 -- both fixed in M13. )

You can select 1 charset detection module at a time. Once selected, the auto detection for the charsets of language(s) you selected will be ON until you turn it OFF.
The charset detector will be engaged even when you have selected a Character Set explicitly via the Character Set menu. If you need to override the effect of the charset detector in effect, choose OFF, and then select a new Character Set from the Character Set menu. Please use the charset detector feature for a variety of web pages in the languages of your choice and let us know how we are doing. File a bug at Bugzilla or send your comments to netscape.public.mozilla.i18n or netscape.public.mozilla.qa.i18n.
Until M10, these charset detectors could be used only by prefs.js settings. This is no longer necessary since the charset detector menu fulfills exactly the same function. The menu now controls what gets inserted into chardet_name of:

chardet_name

here

HTTP charset: Mozilla supports server-generated HTTP charset correctly. (The order of priority is: HTTP charset > Document Meta Charset > Browser Menu choice.)
View | Page Source: works only partially for different charsets.

It works OK:

if the page has a correct server-generated HTTP charset or document-based Meta charset associated with it

In other cases, there are failures of correct display. They fall under 2 types of cases:

The page has been correctly loaded with the use of a charset detector --> the source view will load but may not correctly display characters.
When none of the conditions above holds and the user has loaded the page correctly with the manual change of the Character Set menu --> the source view will load but may not correctly display characters.

CJK line breaking: Mozilla's line breaking implements specifications found in JIS X 4501 with some additional modifications. Read this news article posted to the newsgroup netscape.public.mozilla.i18n by Frank Tang for details.
CJK basic printing: should be working on M13 on Windows and Mac. Not verified to be working on Linux -- probably not.
Mac: Baltic display:

ISO-8859-13: You may experience a problem in Baltic ISO-8859-13 display in that some of the uppercase characters may be missing the diacritical marks above them showing only the base characters. See Bug 9165.

One Workaround:

1) Install a Central European script bundle (CE) from this Apple file. (You need DiskCopy utility to mount this image). After you mount this disk image, rather than using the Installer, open the System file directory by double-clicking on it. In it, you will find among others, CE (script), Slovak (keyboard layout), and slovensk (keyboard layout). Drag these files to your current System Folder. Mac OS will then place them in the right places.
2) Next, get the fonts for Central European from this Apple file. Once you mount this image file with DiskCopy, you will find a number of CE fonts. Drag and drop them onto your System Folder. Mac OS will then place them in an appropriate folder.
3) After steps 1 and 2 are completed, re-start your Mac. You should now see ISO-8859-13 (also ISO-8859-4) characters correctly.

Central European ISO-8859-2 display: There seems to be a Mac bug -- some 8-bit range characters display as "?" even though a correct font exists on the system. See Bug 18095.

Java: Java Plug-ins on Windows. Java plugins probably are not be working on M13. The main reason is that Mozilla APIs sometimes get out of synch with published JRE/JDK plugins. For example, JDK/JRE1.3 plugins don't seem to operate with M13. See Bug 24487 to keep track of Mozilla and Java Plugins for M14. The following instructions are general setup steps for Java Plugins. When Mozilla APIs are in synch with JDK/JRE plugins, you can use these steps to activate Java.

To get Java working on Mozilla, if the installer gives an option to install a JRE package, the following steps will be taken care of automatically. If you choose not to use the installer, or the package you selected does not give you such an option (e.g. the JRE package is not currently included in Mozilla distribution), or if you want upgrade the Java plugins yourself, you need to take some extra steps as described below.

First get the International version of JRE 1.2.2 or later from Javasoft. We recommend using JRE1.3 (Beta at this point) for improved Java support. JRE packages are distributed for JDK releases and Beta version downloading requires registration first. Install the package on your Windows. We find that JRE 1.3 Beta can run more applets than JRE 1.2.2 plugin files and are therefore recommended. Plugin files are also much smaller in size in the latter version.

Note to CJK Windows 95/8 users: If you want to use Java on these Asian Windows 95/98, you must get the international version of JRE which has i18n.jar file needed for conversion from native charsets to Unicode -- otherwise, Mozilla will crash when trying to start. NT4 users will have no crash of this type. If you are CJK Win95/98 users and are not using the international version of JRE and are experiencing startup crashes, then remove the 3 .dll files from the plugins directory and live without Java until an international version of JRE is installed. See discussion in Bug 21305 for details.

Create a directory named plugins in the same directory where the mozilla.exe resides.
Copy 3 files, npjava11.dll, npjava12.dll, and npjava13.dll, from the JRE's bin directory into the plugins directory you created in step 2.
(This part should be optional since Mozilla searches for plugins automatically.) If you have Java Plug-in Control Panel, you can check this from Windows Start | Program menu. The following settings (no others) should be checked.

Basic: Java Plugin, Java Console (optional), Cache Jar in memory
Detailed/Advanced: Use Java Plugin as default, Just in time Compiler is on
Proxy: use the browser setting
Certificates: (none)

Due to a few bugs, some applets simply will not run. Some string display applets do run and so far we have found none can actually display non-ASCII strings. See Bug 17169. If you have specific applets which deal with string display, write your finding to netscape.public.mozilla.qa.i18n.

General: At M13, Editor is now quite usable for a variety of languages both in HTML composer and Plain Text editor (Mail included).
Global IME on Windows: is supported starting in M13 thanks to a contribution from Makoto Kato <m_kato@ga2.so-net.ne.jp> and integration work by Frank Tang <ftang@netscape.com>. Include these 2 people in all bugs related to Global IME.

A Global IME module is an add-on for all language versions of Windows 95/98/NT4. There are 4 Global IME modules (Chinese-Simplified, Chinese-Traditional, Korean, and Japanese). They can be downloaded from a Microsoft downloading site. Once installed, you can input in these languages (CJK) under any non-CJK language Windows versions. These modules also enable CJK Windows users to input in languages not supported by their operating system. For example, Japanese Windows users can install Chinese and Korean modules, etc. However, you should never install a Global IME for a language which is already covered by your OS. For example, do not install Japanese Global IME on Japanese Windows. Windows 2000 comes with options to install improved CJK IMEs. Therefore, users of Windows 2000 should not use these add-ons meant for other Windows.
You can install either a Global IME module by itself or a Global IME with a matching Windows font for that language. The latter is called Global IME with Language Pack. We recommend getting the Global IMEs with Language Pack. Visit this site, read the explanation, and download the modules you like. These Global IME packages will also install usage documentation under Start | Program | Microsoft Global IME.

Copy/paste now I18n-friendly: Basic intra-application copy/paste is now working in all areas of Mozilla for non-ASCII strings. You can copy from Browser or Messenger viewing window and paste into all Edit fields within the application. This should work for all languages we cover at present. (Macintosh does not allow you to copy from Browser window and there seem to be other problems still left in intra-application copy/paste.) Note: The inter-application copy/paste is working partially in M13 -- the status varies from platform to platform. See below for more.

You can copy/cut and paste within the same application

within the same same text area
from one text area to another text area (e.g. from HTML to Plain Text editor text area)
from one text field to another text area under HTML Mail Composer (e.g. from Mail compose subject header to body text area)
from a viewing window (e.g. Browser) to text Edit field (e.g. form, Editor, Mail composer, etc.)

Known bugs: Copy/cut and paste for non-ASCII string is not working in the following inter-application cases. These cases are being worked on and we should get most of this resolved in M14. See 8427 for details. The following paints a general idea of where copy/paste may not be working currently. Generally speaking, some of this is working on Windows but not usually on Mac or Unix. Mac currently lacks support for Unicode clipboard and this is part of the problem. Cf. Bug 10816.

>From Mozilla to another application -- if the other application does not support Unicode clipboard in the target Edit field. (Note: It does not help the matter if the platform does not support Unicode clipboard, e.g. Win95/98.) On Mac and Unix, this function seems to be generally broken.
>From another application to Mozilla -- if the platform does not support Unicode clipboard. This should work on WinNT4/2000 but probably will run into a problem Win95/98 in some cases. On Mac and Unix, this function is probably not working at all for non-ASCII data. The general bug to deal with this problem on all platforms is Bug 24010.

Saving with Editor Character Set menu: On a new document, change the encoding to the one you would like to save the document in and then use the File | Save as menu to save the edited document in that character set. Bugs or comments to: Bugzilla or netscape.public.mozilla.qa.i18n. Here are some known bugs.

Now the document will be saved in a charset you specify via the Character Set menu. (Note: This behavior will change when the International Editor UI specs are implemented.)
Currently this menu does not reload a document. It can only be used to save a document into a different charset at the save time. This menu will be re-worked extensively later.

Basic IME support on Unix: We test Japanese input under Red Hat 6.0 + kinput2 + wnn4 + glibc-2.1.1-6. We need your help on testing other Unix platforms and other language IMEs!
Help test (Japanese) IME on Unix!: We need the following kinds of testing for Japanese IME and others on Unix. Please send your comments to netscape.public.mozilla.i18n or file a bug using Bugzilla Bug Management System for Mozilla.

Testing on other platforms -- our reference platform is Red Hat 6.0.
Testing other XIM-based Japanese IMEs (both public domain and commercial ones such as Wnn6+xwnmo) to see how we are doing. We used kinput2 + wnn4 as our testing environment. We need input from people using other IMEs and servers. Write to us also if you can confirm other IMEs are working. If there are special conditions to be followed, include that information also.

Chinese and Korean IMEs on Unix: We would also like to hear from users of IMEs for Chinese and Korean IMEs. Write to: netscape.public.mozilla.i18n about your findings.

So far we have received reports that XCIN for Traditional Chinese works with Mozilla. For XCIN, see this English page for more info.
Also internally we could get one Korean IME to work. For Korean XIME general info, visit this English page by Jungshik Shin. For hanIM specific info, visit this Korean page.

CJK IME bug status:

On all platforms:

We don't see any major crashing bugs at M13.
Most major bugs in basic operations of CJK IMEs have been fixed but there are some smaller bugs. They should be suitable for fairly heavy use now. Here are some of the current IME bugs.

On Unix: Unix IME is in fairly good shape though bugs remain but it is quite usable in M13.

Some bugs which had to do with the positioning of IME status window have been fixed. Cf. Bug 22326.

Form Password field input bug:

Due to a bug, the form password input is not concealed completely when you engage CJK IMEs -- you can bring up the conversion candidate window and see what characters you are typing. To avoid this bug, turn off the IME and then input a password. Only this mode will work OK for the password field. The Half-width Alphanumeric mode (e.g. Japanese IME) normally works like the direct input mode but for this bug, it is not effective and reveals the input when the candidate window is brought up. Only ASCII input mode should be available in this field. See Bug 16940 for details.

ALT + NumPad Latin 1 input bug:

M13 has an annoying bug in Editor and Mail Composer where if you use ALT + NUM Pad to input Latin 1 accented characters, the input character gets placed one position to the left of the final position. It is also difficult to input Latin 1 accented characters consecutively using ALT+NUMPad method. See Bugs 22206 and 25280.

Notable bug fixes:

CJK IME force commit function has been enabled in some areas. For example, choosing a style menu item or inserting the cursor into other parts of the edit field will force commit, or clicking on a submit button in form.
AltGr combination should now work for international keyboards. There is one glitch remaining -- i.e. a menu will open if the key you happening to be using with AltGr key is also a menu shortcut key. Bug 9333.
XIME status window refreshes its position now as new input is made.

Localizability:

General: One of the key features of Mozilla is that it is relatively easy to localize menus and dialogs UI into any language. See the framework section below for a brief discussion of guidelines. Commercial browsers don't often get localized into languages with smaller number of speakers. If you want to see a fast, next generation browser in your own language, Mozilla offers a great chance to make it a reality.
Voluntary localization projects: Currently 17 voluntary language projects are going and more are likely to join. If you're interested in localizing Mozilla into your favorite language, this page explains it all. Current projects are: Bosnia, Brazilian, Catalan, Czech, Danish, French, Georgian, German, Greek, Hawaiian, Indonesian, Japanese, Norwegian (nynorsk), Polish, Spanish (es-CO), Spanish (es-ES), and Thai. Some of them already have published M13 kits. Check out the Mozilla L10n How-to Page.
Localization framework:

We have published a guideline for localization. Anyone interested in localizing Mozilla into another language should read this document carefully.
Here are some basic ideas to keep in mind when localizing Mozilla. For translating the entire Mozilla, you should read this document and do it in an organized way using leveraging tools to synch up from earlier versions. You might follow the following steps when doing a quick translation work of a few phrases.

Do not localize .xul files directly. All localizations must take place in corresponding .dtd files or .property files.
Localizable strings have now been extracted from .xul into .dtd and .property files. The these files are found under ../chrome/component_name/locale/en-US directory. They match the names of the corresponding .xul files which are placed under:../chrome/component_name/content/defaultdirectory.
Translators need not worry about this, but if you create a .xul file then you need to extract localizable string into a corresponding .dtd or .property file. (If you're creating Mozilla UI via a script rather than by a static .xul file, then you need to extract them into a property file.) To extract .XUL entities into DTD files for localization, read this document.
Mozilla assumes the default charset of all .dtd files to be in UTF-8, and all .property files to be in escaped Unicode. If you change UI strings to your language using non-ASCII data, they should show OK as long as they use the appropriate Unicode encoding format. (You can change menus to Japanese, for example, in ..chrome/navigator/locale/en-US/navigator.dtd file using the method suggested above and then convert the DTD file to UTF-8.)
All non-ASCII .dtd files must be in UTF-8 encoding and .property files in escaped Unicode -- these are Mozilla's default encodings for the resource files. You do not need to explicitly mark the resource files with these encodings, Mozilla will assume that they are in UTF-8 or escaped Unicode even if there are no charset tags.
Using a localized version under an operating system for another language: Some parts of Mozilla are dependent on the operating system widgets for display. This means that there will be some areas (e.g. some part of dialogs, window title, etc.) which will not display correctly if you use, for example, a Japanized version under English Windows.
In summary:

It is best to use localization tools and methodologies mentioned on this page. If you want to do a quick and dirty translation on a few strings for a demo, you should keep the above steps in mind.

UTF-8/escaped Unicode conversion utility:

Use convenient converter utilities such as "uniconv" (for Windows and Unix) or "native2ascii" utility included in the latest JDK.
Mozilla's nsconv conversion utility has been enhanced by "jonas.utterstrom@vittran.norrnod.se"-- it now supports charset aliases: The original nsconv is by the courtesy of Frank Tang. nsconv is installed in the same directory as your mozilla executable. You can use any encoding names recognizable by Mozilla and their aliases checked into the source in using this utility. Here's the basic command line for using this utility:

Usage schema --any one of the following:

nsconv -f source_charsetname -t target_charsetname source_filename new_filename
nsconv -f source_charsetname -t target_charsetname source_filename > new_filename
nsconv -f source_charsetname -t target_charsetname < source_filename > new_filename

You can use the charset names you see within the parentheses of the Character Set menu for source_charsetname and target_charsetname, e.g. iso-8859-1, Shift_JIS, Big5, EUC-KR, etc. Use UTF-8 and x-u-escaped for target encodings.
The utility does not seem to replace an existing file with the new output file. If you have an existing file with the same name as the intended output, first delete the existing file. Or else output into a new file with a different name.

DTD/XML encoding definition supported -- thus you can use charsets other than UTF-8 as the .dtd file charset, but using charset other than UTF-8 is not recommended for Mozilla localization. We assume UTF-8 as default. Cf. Bug 4431.
Notable bugs:

chrome.rdf file: Definitions in chrome.rdf files under locale directories can be used to switch to different chromes suitable for a particular language version, or make other chrome switches. Due to a bug (Bug 21647), this feature is not working well.
Access key and Command key shortcuts are supposed to be appended before an ellipsis character "..." in languages like Japanese but currently Access key is appended to the end after the ellipsis character "..." as in Save as ... (S). See Bug 14110.

Mail/News (Testing done on Windows and Linux only):

Performance: There have been 2 great improvements in M13 and Messenger is now very much usable. We recommend that users give it a try.

Messenger should now be able to handle mailboxes with several thousand messages. For moderate users of mail, Mozilla should be a usable daily mail client. M13 would be a very good chance to get your Mozilla mail experience going and participate in making it better. (Note: In addition to performance improvement with server interactions, improvements in preference settings with Mail Account Setup were also made in M12.)
Message display code has been re-written in M13 to speed up the display of messages measurably. Users of M12 will notice this display speed gain immediately.

Preferences file: prefs.js (Note: Up to M8, the Preferences file was named prefs50.js. This file name is prefs.js instead for all later Milestones.)

General info for M13:

Once you create a profile via the Profile Manager, the rest is very easy to set up with the use of Edit | Account Setup ... menu in the Messenger window. Read this section also for general preferences issues in addition to looking at Mail specific preferences.

Mail Account Setup manager: If you want to learn more about how to setup various mail and news servers, and multiple mail mail accounts, read this document. The future Mail Account Setup specs also have been published here.

SMTP sever setting:

If you have not done so already, after you start up Messenger, choose Edit | Account Setup ... and set the outgoing (SMTP) server and user name. This needs to be done only once but without setting, you will not be able to send out mail.

Password:

When accessing a mail server for downloading messages, you will be asked to provide a password via a dialog. If you want Mozilla to remember your password, use Edit | Account Setup ... menu and select "server" under each one of your accounts. Then check "Save password: box.

IMAP server setting:

Use Edit | Account Setup ... menu to set up a variety of IMAP server related options.

NNTP (News) server setting:

Use Edit | Account Setup ... menu and add an News server. Then when it is added, use File | Subscribe ... menu to add newsgroup you want to read. Currently there is no way to list all the newsgroups on a server. Just add newsgroups you want manually via the Subscribe... menu.
Reading in different languages is now working if the charset parameter is specified in news article headers. You can also use auto-detection modules enabled though the Browser menu to detect and display articles without a charset parameter. At this point, news reading in Chinese will be generally difficult since many Chinese newsgroups contain messages without any charset parameter.

POP Mail settings:

Use Edit | Account Setup ... menu and set up several different options using the server setting under each account.
You can set it up to keep the messages on the POP server after you have downloaded them, too.

HTML vs Plain Text Mail option:

You can set up HTML or Plain Text send option for each server in your account. In case a server is not selected in the Messenger's left pane, the setting for the very first server (on top) on the Account Manager list will be used as the default. In future, the default Mail Send option should become possible through an UI element.

Account Names in non-ASCII characters: For the names you want to give to each of the Mail or News account, you can now use non-ASCII characters. They will be preserved in prefs.js file. Remember, however, that when there is non-ASCII data, prefs.js will be in UTF-8 encoding. If you look in prefs.js with an editor, you will not be able to see the characters correctly unless your editor can display UTF-8 data. If you make changes and save the prefs.js file, your editor must be able to save in UTF-8. Otherwise, the prefs.js will become corrupt and unusable. If you're editing the prefs.js file and if it contains non-ASCII data, first create a backup file and edit this one rather than the prefs.js file itself.
Directory Path names in non-ASCII characters?: You can customize where you store your mail msgs and summary files. At this point, non-ASCII names must be avoided in path names.

Downloading POP msgs & IMAP headers :

The performance in these areas has improved further in M13.
Note: some POP servers don' t handle multiple, simultaneous accesses to the same account well. In such cases, keep only one connection alive to use it trouble-free.

Displaying Mail links with Browser: If clicking on an URL link in a message leads to display in the Messenger window rather than in the Browser window, choose Browser's Debug | URI Dispatching | Enable Dispatching. When you do this, URL links in mail messages will not be shown in the Messenger window but by the Browser window. In the near future, this will be the default behavior and links will not be shown inline in the Messenger window.
How various mail-related international functions are working at M13:

Address Book: supports Non-ASCII (including CJK) input, editing and display. The following features are working.

Non-ASCII Input into card fields
List View pane -- proper international sorting (Windows and Macintosh only.)
Each card view pane -- displays non-ASCII strings
Can re-edit existing cards with non-ASCII entries.
New Msg button on Address Book entries: works and will import any language name into the "To: " header for new mail correctly.
Address Picker on Mail Composer window: works for all languages we support and displays all non-ASCII names correctly.
Address auto-completion is working partially. If an Address Book entry contains non-ASCII characters, they are now displayed correctly. However, trying to match with with non-ASCII characters don't work with M13.
Importing 4.5 or later AB entries: Address book entries import from Communicator 4.5 or later is now possible. Just export your Address Book entries using Communicator 4.5 or later. This will create a file with .ldif extension. Import this file using File | Import menu from the Address Book. (Note: This will not work with .ldif files created by Communicator 4.0x versions since they are not saved in UTF-8 and instead saved in the default charset of the operating system.)
Bugs:

On Unix, sorting in Address Book is not working well.

Multi-lingual mail viewing: This is working on all platforms.

Multilingual viewing is working on IMAP, POP3 and NNTP servers as long as the messages contain properly MIME-encoded headers and body with correct charset parameters.
View | Character Set menu is currently not working to override wrong MIME charset label, or view msgs which have no MIME charset (except for Latin 1) specified.
If you have a multilingual font or several fonts which together cover the Unicode ranges (e.g. Chinese, Japanese, Korean fonts + Pan-European fonts), we use them in displaying mail messages and headers for all the languages we support. We pay attention to the charset parameter in the Content-Type header and switch to an appropriate font. The Character Set menu is not needed to switch to different language views unless the message you're viewing is incorrectly labeled. If you would like a basic mono-weight multi-lingual font for Windows, you can get Bitstream Cyberbit font 2.0 here. Mail font settings are also affected by prefs.js setting as described above in the Browser section --
Earlier there were a few bugs which prevented Mozilla from displaying Thai (Windows-874 or TIS-620) mail messages. They have been fixed and now you can view mail messages sent in these encodings.
Viewing News: is working. Multilingual news articles viewing works if they have correct MIME charsets indicated in the articles. Be warned, however, that newsgroups postings are not always MIME-compliant and this could defeat our charset honoring mechanism.
Bugs:

Sender names do not display correctly in the thread pane except for Latin 1 names. (CJK names display as dots.) They are displayed correctly in the Message view window, however. Bug 8405.

Viewing non-ASCII attachments: generally working but there are some bugs.

Attachments should be viewable if they are of the same charset as the main body of the mail or if it has explicit charset parameter in the attachment headers, or if it contains a valid Meta-charset headers in the attached HTML file. If an attachment lacks charset parameter info and if its charset does not match that of the main body, that attachment cannot be viewed currently even when the Character menu is changed to match the charset of the attachment. A charset detector as discussed above can work on attachments without explicit charset information -- if it is turned on via the Browser menu.
Multiple attachments in different languages: can now be viewed without changing the charset menu if each attachment's header contains a correct charset parameter or if a document contains a valid Meta-charset information. If you send a message from Mozilla with multiple attachments and if each attachment has a meta charset tag, Mozilla will create a content-type charset parameter for each attachment from the meta-tag information.
Latin 1 attachment to ASCII msg: In M12, if an attachment contained raw 8-bit Latin 1 characters and was attached to a mail body with an us-ascii charset parameter, Mozilla did not display these attachments correctly. We fixed this problem in M13 by assuming ISO-8859-1 instead of ASCII as the message charset in such a case. See Bugs 20997 & 22209 for details.
Japanese attachments and auto-detection:

The auto-detection module set for the Browser via its Auto-Detect menu will also detect the charset of mail attachments. See above on how to set an charset detection module.
Currently there is a bug which corrupts Japanese EUC-JP attachment display. To work around this problem, we have put in a mail specific charset detector which only works in Messenger under Windows only. (Note: Eventually this detector will be removed when the EUC bug is fixed.) When this is set, this detector rather than the Browser detector will be used in Messenger. This detector will be ON even when the Browser detector is OFF. For those wishing to view Japanese EUC files attached to mail messages, we recommend that this workaround be put in place. There is no UI for this but this is how you can use it:

In the prefs.js file, insert the following line:

user_pref("mail.charset.detector", "jaclassic"); <-- this is basically a detector module used for Communicator 4.x.

Printing: Basic printing is enabled. Currently it is rather primitive. Headers don't seem to be printed -- only body text.

View | Character Set menu and thread pane reloading:

The menu change causes the thread pane to reload properly. This makes it possible to display non-MIME-encoded headers which don't match the current Character Set menu setting. Headers, body, and attachments without MIME charset information may not be displayed properly, however, even if the Character Set menu is changed.

IMAP and Local non-ASCII folder names: Latin 1 names display OK. Multi-byte folder names (e.g. CJK) don't display well yet. Cf. Bugs 7130 (IMAP), 7844 (Local).
International Sorting for Thread pane headers: works well in the Subject headers on all platforms with some problems still left on certain Unix locales. CJK characters are not displayed correctly in the Sender field and therefore cannot be tested. Sorting should be done according to the sort default for the language of your operating system. Date/Time sorting is also working as it should.

Linux sorting:

There seems to be a problem with Latin 1 sort -- this is under investigation.
Also sorting is working for some Japanese locale names but not others. It might have to do with locale name aliasing. This problem is under investigation. Cf. Bug 18338.

International Date/Time format: now works for NT4, Win9x, and Mac for all locales. The format will be used according to your OS's date/time format setting.

Sending Latin 1 & Japanese attachments/pages:

File | Send Page works in addition to attaching a local file to a message.
Note that Mozilla will append a charset parameter to the attachment headers if the page contains an HTTP-Equiv meta charset tag.

Send-related bugs at M13: Here are some send-related bugs at M13.

If the message you're trying to reply to or forward as inline has an attachment displayed inline, none of the attachment is quoted. Forward as attachment does work, however. Cf. Bug 23931.
Sending page with a meta charset tag will mark the attachment with an appropriate charset parameter but sending a page with HTTP charset does not add this charset info. This problem has been fixed in M14. See Bug 24940.
At M13, reply/forward does not initially set the charset to the same one as the original mail. This has been fixed in M14 to reflect the original mail's main body charset. See Bug 3979.

Sending messages in other languages: View | Character Set menu for New Mail Compose window is working for sending mail for many additional languages. Switch to the charset you want to compose a message in and then compose the message. You will not see a checkmark next to the menu item yet, however. Let us know how we are in sending messages in other languages. Send your report to: netscape.public.mozilla.qa.i18n.
Composing Latin 1 mail messages:

In sending 8-bit range characters with HTML mail under Latin encodings, starting with M11, we used 8-bit characters rather than HTML entities, and certain special characters not in the chosen encoding were turned into CERs (so-called HTML entities) or NCRs (numeric character references). We changed this back at M13 to using HTML entities for all non-ASCII range of the Latin 1 table.
In sending 8-bit range characters with Plain Text mail, we will generally use QP-encoded characters. Those characters not in the chosen encoding, e.g. the EURO under ISO-8859-1 is turned into a "?" symbol. We are considering more user-friendly spec for this currently.

General Fallback strategy for sending characters not found in the chosen encoding:

CERs or NCRs will be used in HTML mail.
"?" will substitute for non-existing characters under Plain Text send option. In future, we may offer an option to send in UTF-8 or some other encoding which support the characters in question.

Domain Name completion: is now working. An user ID only input will be automatically completed with the default domain when the Enter key is pressed.
Message Send Status summary for Latin 1 and Japanese: No indicates that the functionality is not working well.

Message send feature	Latin 1 (ISO-8859-1)	Japanese (iso-2022-jp)
Header (subject, address)	Yes	Yes
Body - HTML	Yes (8-bit characters are sent as is with HTML entities. )	Yes
Body - plain	Yes (8-bit characters are sent as is with QP. When the chosen charset does not contain the character, "?" is used in its place currently.)	Yes
Reply/forward header	Yes	Yes
Reply/forward body html	Yes -- POP mail, IMAP, NEWS (but some bugs)	Yes -- POP mail, IMAP, NEWS (but some bugs)
Reply/forward body plain	Yes - IMAP, POP, News. (but some bugs)	Yes - IMAP, POP, News (but some bugs)
Reply/forward inline attachments	No attachment is quoted. Bug 23931.	No attachment is quoted. Bug 23931.
Reply as attachment	Yes.	Yes.
Send Attachment(s)	Yes (Send - local file and web page)	Yes (Send - local file and web page.)
Copy/paste into headers and body	Yes (accented characters copy OK)	Yes (works OK within Mozilla)

Notes on Composing Latin 1 and Japanese Mail messages:

Composing Latin 1 Mail:

Copying/pasting accented characters into the headers and body works from anywhere within the application where copy is enabled, e.g. Messenger Mail window, Browser window. You can also copy non-ASCII data from Communicator 4.x into Mozilla.
Keyboard input into headers (e.g. subject) also works for accented characters. Using the English keyboard for Latin 1 high-bit input, ALTGr + 0+Number Keypad method works, e.g. Right ALT key + 0232. There is an annoying bug about ALT+NumPad use -- see the Editor section for more.
Make sure to switch the View | Character Set to your chosen Character set name before you send out a message.
Basic MIME compliance is there: Header Q encoding, and Body QP encoding for accented characters.

Composing Japanese mail:

Basic Japanese input works for body. Japanese input/copying into the headers and body also work from within Mozilla. You can also copy JPN data from Communicator 4.x into Mozilla.
Mail goes out in ISO-2022-JP. Header is B-encoded. (The Kanji-in escape sequence is that of JISX0208-1990/83. )
Make sure to switch the View | Character Set to Japanese (ISO-2022-JP) before you send out a message.

Sending other charset mail -- is enabled. Please try out these new charsets! For example, Central European, Cyrillic, Greek, UTF-8, Thai, etc.

Though the mail text body can sense what keyboard you have selected and will switch font accordingly, there may be mapping bugs with some international keyboards. If you find a bug with your charset/language, please file it here.

Mail/News (for Mac)

We don't currently test Mac for international features. Though we cannot vouch for accuracy, many of our Windows/Linux features should be working on Mac also.
