GISWxprintglue) package as drop-in way for installation.
If you attempt to run Mozilla on Mac OS using a language pack (such as the Japanese Language Pack) and a Language Kit, all menu bar items will be incorrectly displayed. To resolve this problem, register Mozilla using the Language Register. For instance, if you're using the Japanese Language Pack and the Japanese Language Kit, register Mozilla as a JA application.
If you have Red Hat Linux 6.0, you can't launch Mozilla if Java 2 is installed. The problem doesn't occur with Red Hat 6.1 or higher. (Bug 58259)
When using a window manager from the twm family without the DecorateTransients option, pop-up windows such as Find, Save and Preferences will not function. To work around, set the DecorateTransients option in the window manager's rc file. (Bug 78928)
Note: It is recommended that you uninstall previous versions of Mozilla before installing Mozilla 1.3 Beta. This will not delete your bookmarks, history, cookies and other information which is stored in your profile directory.
Windows Users: If you get the message, "uninstall.exe file is linked to missing export shell32.dll", delete %TEMP%\ns_temp.
Multi-user installs: To install Mozilla for multiple users on Unix, install as normal, then create the following script in your Mozilla directory, make it executable (chmod u+x <scriptname>), and run it as a user with write privileges to the mozilla directory (e.g. root). Do not run this program as su[do] root. (Bug 52653)
#!/bin/sh dist_bin=`dirname $0` MOZILLA_FIVE_HOME=$dist_bin LD_LIBRARY_PATH=$dist_bin export MOZILLA_FIVE_HOME LD_LIBRARY_PATH $dist_bin/regxpcom $dist_bin/regchrome touch $dist_bin/chrome/user-skins.rdf $dist_bin/chrome/user-locales.rdfYou should then be able to run that installation of Mozilla as any user who has permissions to access it.
When you install language packs and other .xpi files, downloading pauses until you click the browser's Stop button.
If you receive the message 'The program must close to allow a previous installation to complete' when launching, it means that file cleanup after an additional installation has not completed.
Windows: It is strongly recommended that you exit all programs before running the setup program. Also, you should temporarily disable virus detection software.
Windows and Linux: To run Java applets, you must install
the Java Run Time Environment
Windows: When using installer builds, everything should Just Work without any help.
See the Java section for more details about Java version compatibility.
Windows: If you're using the Installer build and you already have JRE 1.3.0_01 on your system Mozilla should recognize it. If you've manually set the pref to disable automatic plugin searches then you can do the following to get Java working: After the JRE is installed on your machine, copy NPOJI610.dll from the install directory (something like C:\Program Files\JavaSoft\JRE\1.3.0_01\bin) to your Mozilla plugins directory (something like C:\Program Files\Mozilla 1.3b\bin\plugins).
Linux With tar.gz builds on Linux, after the JRE has installed, put a symlink to java2/plugin/i386/ns610/libjava.oji.so in your mozilla1.3b plugins/ directory. (Note copying the file instead of making the symlink will cause Java to crash)
With Linux RPM builds, you must install Java as the root user.
Revoked certificates using OCSP may still appear in the Certificate Manager verified as "True". (Bug 91530)
Windows, Mac OS and Linux: Personal Security Manager (PSM) provides security (cryptographic) features for Mozilla.
Windows: Some software firewalls may block Mozilla from properly accessing the Internet. If Mozilla is not working properly, check that your firewall settings allows Mozilla to connect to the net. If your receive a warning from ZoneAlaram that Mozilla attempts to set itself up as a local server, it is due to Mozilla communicating with PSM which is required to access secure Web and mail servers, and you should allow Mozilla access.
To install Mozilla by downloading the Mozilla installer, follow these steps:
To install Mozilla by downloading the .zip file and installing manually, follow these steps:
To install Mozilla by downloading the Mozilla disk image, follow these steps:
You must run Mozilla at least once to complete autoregistration and for the compreg.dat file to be written to the installation directory. If a different user (other than the person who installed the product) runs the program first, a core dump will occur. (Bug 49345)
Note: To run Java applets, you must install the Java Run Time Environment (JRE) v1.3 plug-in.
Note: These instructions use the bash shell. If you're not using bash, adjust the commands accordingly.
To install Mozilla by downloading the Mozilla installer, follow these steps:
mkdir mozilla1.3b) and change to that directory (
cd mozilla1.3b) and decompress the archive with the following command:
gunzip -dc moz*.tar.gz | tar -xvf -(This places the installer in a subdirectory of Mozilla named mozilla-installer.)
To install Mozilla by downloading the .tar.gz archive file:
mkdir mozilla1.3b) and change to that directory (
cd mozilla1.3b) and decompress the file with the following command:
gunzip -dc moz*.tar.gz | tar -xvf -(This creates a "mozilla" subdirectory under your mozilla1.3b directory.)
To hook up Mozilla complete with icon to the GNOME Panel, follow these steps:
Installing RPM builds: The Red Hat RPM builds are created to work with the default Red Hat 6.x and Red Hat 7.x installations. Using these RPMs on SuSE requires installation of the gdk-pixbuf package. (Bug 85218)
To be able to sync between Mozilla's address book and your Palm, choose Address Book Palm Sync Install in the Mozilla group in the Start Programs menu. Note that if you set up your Palm to sync its address book with Mozilla, the address book will no longer sync with the Palm Desktop.
Once you have done this you can connect your Palm device and hit the HotSync button on your Palm cradle. This should bring up the HotSync Manager dialog on your desktop and should start Mozilla. Once sync is complete, close Mozilla and then restart it and open Mozilla Address Book to verify the sync.
Some Palm users may need to add an extra step to this process and add a registry key by hand.

Mac OS and Windows: Using ATI video drivers will lead to random crashes on many sites. Mac OS ATI driver versions affected: All (?) Windows ATI driver versions affected: 220.127.116.1118 (Mac OS) Workaround: set your screen to 'Thousands of colors' rather than 'Millions'. (Windows) Possible Workaround: Revert to an older driver (6094?)-- Untested (Bug 101055)
Linux: Keyboard shortcuts on Linux now use Ctrl instead of Alt as the modifier key, while Alt is used for menu shortcuts. If you wish to modify these shortcut keys, add the following prefs (instructions here):
(This changes the accelerator key from Ctrl (17) to Alt (18).)
(This changes the menu access key from Alt (18) to none.)
Linux: Clicking the middle mouse button in areas without links may lead to alerts popping up. (Bug 96972)
Linux: You must have your X server properly configured to enable mousewheel scrolling. 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: Mousewheel scrolling does not work with all drivers. If you have problems, try updating your driver or disabling any "helper" programs that your mouse uses. If you have a Logitech mouse, you can either upgrade the driver (to at least v9.60) or enable the "Microsoft Office compatible scrolling" option in the Mouse/Buttons control panel. (Bug 33732)
Windows: old drivers of Synaptics touchpad may not have scrolling enabled for Mozilla. You can get a new driver at http://www.synaptics.com/support/downloads.cfm .
Mac OS: Mousewheel scrolling does not work with all drivers. If you have problems, try updating your driver or disabling any "helper" programs that your mouse uses.
If Mozilla is locked up but doesn't seem to have crashed, make sure there are no dialog boxes still open. Close each window on your desktop one at a time and if you uncover a dialog window, dismiss it. If you have multiple desktops, repeat these steps for each desktop.
This problem may affect Linux users downloading plugins. Follow these steps to resolve the problem:
Form Manager is not fully implemented in the Japanese version of Mozilla .
Many Linux systems (in particular, Red Hat Linux systems) have bad Arial fonts. (Bug 46415) If many Web pages, especially those using the Arial font, look unclear, small, or hard to read, the following links explain two ways you can change your font server to get better Arial fonts:
If that doesn't work, you may be able to fix the problem by renaming or removing /usr/share/fonts/ISO8859-2. For instance, enter the following command:
mv /usr/share/fonts/ISO8859-2 /usr/share/fonts.ISO8859-2
and then log out of Linux and log back in again. You can always undo this, if necessary, by entering the following command:
mv /usr/share/fonts.ISO8859-2 /usr/share/fonts/ISO8859-2
Mozilla needs to be configured to work properly with proxies such as Junkbuster that do not support the most recent HTTP specification. By default, Mozilla tries to use HTTP 1.1. To use Mozilla with a proxy that only supports HTTP 1.0, change the HTTP Version from 1.1 to 1.0 in Edit | Preferences | Advanced | HTTP Networking | Proxy Connection Options. (Bug 38488)
Mozilla only accepts hostnames for manual proxies. If you migrate a Communicator 4 profile, you will need to change the settings manually. Communicator 4 allowed URL's in manual configuration, but Mozilla does not. If you migrate a profile configured this way, you will need to change the URL to a hostname and port number. (Bug 30387)
In Profile Manager, if you rename a profile to a name you previously used, all your preferences may be lost. Workaround: If you rename a profile, use a unique name. (Bug 113203)
To make a manual change to preferences, do not edit prefs.js. Create a new text file, user.js, in the same directory as prefs.js. Entries in user.js will override entries in prefs.js, if necessary. (Bug 142590)
If you have a single profile from Communicator version 4.5 or later, that profile is automatically copied and converted for use with Mozilla . Profiles from earlier Netscape versions cannot be converted.
If you have multiple profiles to copy and convert, the profile manager dialog box appears. Click the profile you want to use and then click Start.
If problems occur during installation and your Communicator profile was not
copied and converted, you can still use your profile. Launch
from the command line, adding the "
(that is, type "
mozilla.exe -installer" on the command line)
, or reinstall
to see the profile manager dialog again.
If the Location Bar does not respond to the Enter/Return key, you can use the temporary workaround of pasting the URL into File | Open Web location. To fix it, close Mozilla , then delete your history.dat and localstore.rdf. (Bug 90337)
Using Windows 98 with some ATI graphics adapters will result in occasional corruption of inline images as rendered on web pages. This is an ATI graphics driver bug. (Bug 104992)
If a username or password is embedded into a URI in the form of http://username:email@example.com. Mozilla will not warn the user of this when the user follows the link. URI's with long usernames in the form of http://firstname.lastname@example.org could deceive users into thinking they were going to mozilla.org when they were really going to fraudsite.com. (Bug 122445)
If the user is downloading a file in the background and the user exits from the File menu, the download will abort without warning. Workaround: Only exit after downloads finish. (Bug 28385)
When browsing with many tabs open (more than 25), some tabs may stop responding. Workaround: use multiple browser windows.
Additional Internet Search Engines can be obtained at http://mycroft.mozdev.org/
The "View Frame Source" feature is not available from the View menu; however, it is available in the context menu. To see the context menu, click the left mouse button to put the mouse pointer in the frame and then click the right mouse button (Control click on the Mac OS). (Bug 47139)
While enabling HTTP pipelining may significantly improve page load times, it can prevent some websites from loading correctly. If you experience problems loading a website, please verify that HTTP pipelining is disabled and try again (see Preferences->Advanced->HTTP Networking). HTTP pipelining is disabled by default. (Bug 144607)
Mozilla may not be able to connect to some secure (HTTPS) IBM Web servers. This is a problem with the servers' software, not with Mozilla . (Bug 54031)
If you use "Last page visited" as your Home (starting) page, if the last page you viewed had frames, it may not be displayed correctly when you next restart Mozilla . (Bug 58613)
Accessing pages with a Uniform Naming Convention (UNC) requires 5 slashes (file://///). (Bug 66194)
Linux: On Linux, there may be problems with ESD Audio and Flash. (Bug 85772)
Hourglass cursor, progress meter, and throbber do not stop spinning although downloading has been finished. Status bar says "Transferring data from ..." when page is done loading. (Bug 39310)If you're unable to remove user-defined helper applications try the following:
Bookmarks cannot be rearranged if you have sorted them. To rearrange them, select Unsorted from the View menu, or click the Name column header until the arrow disappears. (Bug 64768)
You cannot save two differently named bookmarks for the same URL. (Bug 51683)
Mac OS: The horizontal scrollbar in the View Source window might be missing. Resize the window to see the scrollbar. (Bug 56488)
Moving or copying a labeled message will not retain label in destination when filing across accounts:
In the Mail/News Account Settings: Server Settings dialog box, any changes you make to local directory settings won't take effect until you exit and restart Mozilla . (Bug 2654)
Mail account identity is not stored along with an unsent message. (Bug 59548)
Linux: You may encounter problems if you install Mozilla in a root user environment then run as another user. Problems include saving to Sent folder, Drafts, Templates or general authentication problems. (Bug 49397)
The Mail & Newsgroups Account Settings dialog box does not display correctly at lower monitor resolutions such as 800 by 600 or 640 by 480. If possible, increase your monitor's display resolution above 800 by 600. (Bug 82122)
SMTP over SSL often doesn't work to port 465 (the standard secure SMTP port), or any port other than 25, due to a protocol (STARTTLS) handling problem. Workaround: Use port 25, and the connection should work and still be secure if you choose 'always' or 'if available'. Otherwise, Mozilla will hang. (Bug 98399)
Mozilla does not integrate with AOL Mail and Netscape WebMail, as Netscape 6/7 do. If you share your Netscape 6/7 profile with Mozilla, you may be able to see headers for messages in the account's Inbox if you have previously checked one of these accounts in Netscape 6/7, but you will be unable to interact with the messages. To access your AOL Mail, WebMail, or Netscape Instant Messenger, you need to use Netscape 6/7.
You may not see the message header (From, Subject, Date, To, Cc, and so forth) when you read messages. This problem often occurs when you switch mail folders or newsgroups. To see headers, resize the window or the message content pane. (Bug 39655)
In some cases you can't view more than one HTML/Web page attachment to a message in the mail window. The attachments will not all be shown or you may experience a crash when attempting to display them. (Bug 38398)
Attaching RTF files to emails may result in them being sent such that most readers will not be able to read them. If you plan to send RTF attachments, you should go to Edit>Preferences>Navigator>Helper Applications, select "New Type", and enter:
MIME Type: application/rtf Description: Rich Text Document Extension: rtfand then select OK to close the dialogs.
Imported Netscape Communicator address books appear in Mozilla as a separate address books. (Bug 41590)
To import Outlook address books, you must have the default mail client set to "Microsoft Outlook" in Microsoft Internet Explorer. Do this:
1. Launch Internet Explorer.
2. Click Tools in menu bar, then click Internet Options. The Internet Options dialog box appears.
3. Click the Programs tab and select "Microsoft Outlook" as the default e-mail client.
4. Hit OK and exit Explorer. (Bug 90206)
(Windows) You may need to try more than once before Outlook Express address books are imported successfully. (Bug 90206)
Copying a large number of addresses between address books may cause crash. (Bug 82991)
If you have multiple filters configured for a mail account, incoming messages will continue to be evaluated against each filter (in the order listed in the Message Filters dialog) until a filter action of Move to Folder or Delete is executed. This differs from Communicator 4.x where any filter action would stop further filtering on a message. (Bug 30081)
You must exit and restart Mozilla to see the effect of a change to the option: "show All IMAP mail folders" or "show only subscribed IMAP mail folders." To access this option: click the Advanced button in the Server section of the Account Settings dialog box. (Bug 38943)
The Subscribe dialog box may not work with news servers that require authentication. If you open a password-protected newsgroup you may be prompted more than once for the user name and password combination.
Mozilla may temporarily hang during LDAP autocomplete if network connectivity is broken. Specifically, if the LDAP server in question is unreachable (network connectivity problems, including taking a laptop outside a firewall), the entire app will hang when attempting to contact that browser. The app will begin responding again after about 10 seconds (the length of the TCP timeout). (Bug 79509)
Moving/Copying a downloaded message (while offline) will result in not being able to read the message at the new folder while you are offline. Workaround: Go online to read it, then re-download the message to have it accessible when you are offline. (Bug 78809)
When starting Mozilla, if you only have one profile, both of the Offline preferences for startup mode ("Ask me if I want online or offline mode", or "Use my previous online/offline state") do not work. Mozilla will always start in online mode. To go offline, from the File menu, choose Work Offline. (Bug 82487)
If the user starts Mozilla in offline mode (clicking the work offline checkbox in the profile manager), then tries to reply to a message while in offline mode, or double clicks on a message (which brings it up in a separate window), in some instances the application might crash. (Bug 92368)
ChatZilla is not finished, but is usable if you're willing to accept a subset of the commands offered in more mature IRC clients. A large percentage of ChatZilla users experience crashes, odd behavior, rash, shortness of breath, and an urge to fix bugs. If you would like to contribute, please tell us in the netscape.public.mozilla.rt-messaging newsgroup, or send an e-mail to email@example.com.
If you are not familiar with IRC, please check out the FAQs available at www.irchelp.org.
Start Mozilla with the -chat option to start ChatZilla, or select it from the Window menu.
Once you've floated all the views out of the main window, no drop targets remain to bring them back. If you have "Save Default Layout On Exit" checked, and you exit, you will appear to be stuck like this. (Bug 151785)
As a workaround, show the Interactive Session from the Show->View/ Hide menu, and type "restore-layout factory".
When Publishing in Composer, if the Publishing URL, file name, user name, or password contain any special characters (such as "@") that need to be escaped, then Composer creates a duplicate site entry each time you publish the document. To work around this bug, choose the original site name from the Site Name list in the Publish dialog box before publishing the document again. For example, some ISP users have usernames that are also their email addresses, e.g., "firstname.lastname@example.org". After publishing to this site, the next time you use the Publish dialog, the username from the document URL will appear as "janedoe%40ispname.net" (the "@" was escaped during publishing). Since Composer can't find this entry, it creates a duplicate site name. (Bug 141819)
You may not be able to simultaneously edit a document using both Composer and another editor. (Bug 37089)
You can't apply a font style across paragraphs and images. Font changes must be done within each paragraph.
Applying a font style across several words yields multiple font tags in the HTML code.
When the background color on a page is set, only the frames behind the lines of selected text are colored. Resizing the window triggers the proper repaint.
After applying a color to text, the text may appear partially highlighted.
Certain pages (such as ones that set frames) can't be edited. However, you are still able to choose the Edit Page option in the File menu for such pages. An editor window opens, but you are unable to edit the page.
File|Open Web Location, selecting to render in Composer does not open document in Composer. (Bug 71426)
You can not print HTML Source. (Bug 82239)
Hourglass does not show when application is busy. (Bug 83300)
Some element icons do not render in Show All Tags mode. (Bug 88036)
List editing can cause nested lists to outdent to next level list. (Bug 98547)
Remove option from personal spell check dictionary does not work. (Bug 43348)
If the cache preference is set to "Every time I view the page" and a new document is created, toolbar icons may be disabled on the toolbar and the caret may be missing. Workaround: Do not set the cache preference to "Every time I view the page." (Bug 97633)
When visiting a SSL enabled site, the lock icon will take on a yellow background, and will not indicate the strength of the SSL encryption used, whether it is 40 bit, 56 bit, or 128 bit. (Bug 74320)
Restoring a certificate to a smart card can take a long time. No feedback is provided while restoring a certificate to a smart card, which can take a long time since smart cards are relatively slow devices. As a result, it may appear that the restoration is not happening. (Bug 52321)
For security reasons,
does not allow connections to certain ports. To override this on a per-port
basis, add a comma separated list of ports to defaults/all.js (in your
Note that this pref only works in the
all.js file in the
Mozilla installation directory and it
affects all users of the installation.
It does not work if you add it to the
files in your personal profile directory.
For example, to unblock ports 1, 3, and 7, use the following line:
For security reasons,
does not allow web content to link to local files. An error like:
Security Error: Content at url may not load or link to file:///something
links to local paths it is recommended that you drag the link
to the location bar and then drop it on the webpage. If you
really don't like the security check and are willing to risk
all files on your system and that your system can access then
you may add the following line to user.js in your personal
Do not share a profile between Netscape and Mozilla nightly builds. Doing this can lead to unpredictable results, some of which may include loss of Search settings and preferences and unchecked growth of the Bookmarks file (large enough to freeze your system). It is best to create a new profile for each or manually copy (and change the name) an existing profile. (Bug 137164)
If you are using the Classic theme, some preference panels may be displayed incorrectly or may have missing elements. If you view a different preference panel and then return to the one you're working in, the display is corrected. (Bug 51241)
Preferences window initial size doesn't always give hints on all options available. Resize the window from its lower right corner to see them all. (Bug 53375)
When you close the last window, Mozilla will unload itself and reload itself this may take a while. This will probably result in lots of disk thrashing. (Bug 143764)
When you close the last window, the icon in the tray will disappear and reappear at the end of the tray. (Bug 146340)
For more information on plug-ins, see the plugin doc at mozdev.org.
Windows: The Adobe SVG plugin crashes. Workaround: Don't copy it (NPSVG3.dll NPSVG3.zip) into your plugins folder. If you want to view SVGs, there are Mozilla builds with native SVG support. (Bug 133567)
Linux: The Flash plugin context menu does not disappear when you click outside the plugin area to dismiss it. Workaround: Click inside the plugin to dismiss the plugin context menu. (Bug 63182)
Linux: Mozilla crashes while playing Flash content on a remote X display. No workaround present other than not using remote X display. (Bug 58937)
Linux: Loading a page that contains a Flash plugin may cause Mozilla to lock up if you are using an audio application. (Bug 58339)
Plugins installed for Communicator 4.x may not be available for Mozilla . Workaround: install these plugins in the Mozilla Plugins folder.
Windows: Microsoft Media Player file embedded in web pages may not work. (Bug 66015)
Mac OS: Mozilla now scans for plugins in the system's "Internet Plugins Folder" first.
Windows: Some users might not be able to print on Windows 98 or Windows ME with the default spool setting. The workaround is to go into printer properties, choose details tab, choose spool settings, and then choose print directly to printer. (Bug 130083)
In Print Preview, plugins are not shown. (Bug 134002)
Linux: Mozilla has a 2nd print module called Xprint which supports
features like CUPS, LPRng,
MathML and TrueType
font support and enables Mozilla to print text written in languages and scripts
like Arabic, Chinese, Cyrillic, Greek, Hebrew, Indic (Devanagari, Tamil,
etc.), Japanese, Korean, Polish, etc.
To learn how to install Xprint, go to Mozilla's Xprint module project pages and http://xprint.mozdev.org/.
Note that Mozilla's Xprint module is explicitly disabled in RedHat RPM builds (see bugzilla.mozilla.org bug 133534).
Printing newsgroup messages with images leads to a crash. (Bug 92659)
Linux: There are several bugs involved with the PostScript module that are not present in the Xprint module (Bugs 6810, 24824, 28088, 31356, 52058, 52420, 63737, 65784, 67338, 68373, 80190, 82982, 85207, 107756, 119263, 119265, 123144, 123408, 125006, 126602, 127422, 131071, 131088, 135695, 137115) 144376, 144418, 150897, 152882, 154027, 157132, 158025, 161827, 166780, 168614, 172525, 175879, 176319, 176938, 177211, 177494, 179448, 179538, 182324, 183688, 185895, 187184, 189884, 189884, 194761, 194830, 195043 195043, 195206, 196306, 198165 ).
When going to a site that requires the user to authenticate with HTTP to download a Java applet that also requires authentication, the user will have to login twice with the same username and password. (Bug 60304)
Java J2SE releases previous to 1.3.0_01 will not work with Mozilla. Problems have been reported with JRE 1.3.1. For best results JRE 1.4.1 is recommended. Mozilla has been tested with all 1.3.0_* versions of the JRE, and JRE 1.3.1, and beta versions of JDK 1.4.
Running J2SE in 256 color mode may cause a flickering problem.
Linux: LiveConnect support now works if you use Mozilla 1.3 Beta with JRE 1.3.1. Additional LiveConnect problems are being addressed in JDK 1.4 as mentioned above.
Sun's JRE will crash at startup if your useragent does not begin with Mozilla/5. It might print
Expected a version > 5! Version = 4
The workaround is to not forge a useragent whose version is less than 5 if you have the Sun JRE plugin in your plugin directory. this preference would appear in pref.js as something like:
user_pref("general.useragent.override", "Mozilla/4.0 (compatible; MSIE 5.0; Windows 98;)");(Bug 83376)
If Java doesn't work, make sure the following is true:
Copy the NPOJI610.DLL from C:\JDK*\jre\bin to "\plugins" directory of your installation.
Make a symlink to /usr/java/j*/jre/plugins/i386/ns610/libjavaplugin_oji.so in your mozilla1.3b plugins/ directory. Do not copy the file, but instead make a symlink to it.
Mozilla has been designed to display many different languages without extra steps. The user should be able to browse and use e-mail without complicated setups or efforts when necessary fonts are available on the system.
Mozilla can be used with more than one language pack, which lets the user change the menu language and relevant URLs.
Contents of Sidebar tab and Bookmark will not change when you choose another region -- they are bound to a specific profile. (Bug 87939)
If you are using Chinese, Korean or Japanese language Windows 9x/ME and launching fails or crashes, read the Java section of the Known issues section below for possible causes.
You may be unable to print out Japanese characters from Win98-J with HP Laser Jet driver (Japanese version). Workaround: Install the driver that comes with the Japanese Windows 98 installation CD. (Bug 86989 )
If you have WinME-Ja, you may not be able to print to a HP LaserJet 5Si/5Si MX using the HP LaserJet 5Si/5Si MX PS printer driver In this case, you should change the driver to HP LaserJet 5Si/MX. (Bug 86989)New: On platforms which support file names in Unicode, it is possible to create files and folders bearing names in scripts which fall outside of the system locale. Browser operations which involve such folder or file names may not succeed, e.g. saving into such a folder, or opening a file whose path contains such characters. Using only characters supported by the default system language avoids this type of problems. (Bugs 58866, 100243, 100344, 100364, 100396, 101573, 128380, 104305)
On Japanese Windows XP, the desktop icon and Mozilla Program Folder cannot be removed after Mozilla program is removed through a program uninstallation via the Control Panel. You can manually remove them. (Bug 125104)
Mozilla does not support Dynamic Fonts. (Note: It was supported in Communicator 4.x.)
Auto-detect All/Universal may not be able to detect encodings on pages which don't supply document encoding information. You can increase the accuracy if you choose other auto-detection modules with a smaller scope for detection , e.g. Chinese, Simplified Chinese, East Asian.
Support for the Unicode surrogate range is not currently available for Linux. (Bug 127713.)
A Composer page cannot be saved into ISO-2022-KR using the Save As ... menu because there is no converter available from Unicode to ISO-2022-KR. ISO-2022-KR will be eventually hidden in the Save as .. menu. (Bugs 132070 and 133615.)
When opening a file under a folder with multi-byte folder name, the path name in multi-byte characters is escaped in the title bar of Composer window. (Bug 136221.)
Linux only: Bold and Italics styles may not work on ASCII characters when editing a CJK page. This is most likely to happen on CJK locales without good ASCII fonts. For example, you may be using language open-source CJK locale support files. On commercial Linux distribution, particularly recent ones, the support files contain better CJK fonts and this problem is less likely to occur. (Bug 91145)
Mac OS: Non-ASCII non-Latin 1 info stored in Internet Config will not show correctly in auto-fill fields such as "Your name" field in the Mail account setup dialog. If this happens, you can manually correct auto-filled entries. (Bug 5721)
Filtering by body key is not implemented.
The Character Coding menu cannot correct the thread pane display of non-MIME encoded headers. This is by design. If the message displayed lacks MIME charset information, the thread pane display obeys the default message display charset set via the folder properties dialog (set via the menu Edit | Folder Properties ...). Correctly setting this option to the charset most often used in the user's mail viewing helps avoid display problems of this type
Some cases have been reported in which Windows 9x/ME Japanese users have a problem starting Mozilla when there is a prior installation of older JDK or JRE under the operating system in use. The JRE 130_02 (or later) that Mozilla users can download from a Netscape ftp site contains many fixes since the official release of JRE 1.3. If you are using an older version of JRE 1.3 or the US version of JRE 1.3 under Japanese/Chinese/Korean Windows, you may experience this non-start problem.
To determine if the non-starting problem is due to Java installation, follow these steps:
If you have the Java problem as described above or want to install updated JRE 130_02 (or later) that you can download from a Netscape ftp site, follow these steps (Note: This type of problem has not been reported for Windows NT4/2000, but if you experience this problem on the latter two platforms, follow these steps for those platforms also):
Mac OS and Linux: Display of non-ASCII characters (particularly Chinese/Korean/Japanese) in applets may not work without correct font settings in font.properties files. Windows releases ship with modified font.properties files. This document may be helpful to Mac and Linux users.
Quality Feedback Agent collects data about Mozilla in the event of a crash. Such information helps Mozilla developers to quickly isolate the cause of a crash and then correct it. The software does not collect any sensitive information such as Web sites visited and passwords. Reporting crash data is one of many ways in which users can help improve the quality of the software. Participation is not required but highly recommanded.
On Windows, if you are using automatic proxy configuration, you need to edit your talkback.ini file for Quality Feedback Agent to work.
Mozilla is very configurable, however there is not room in the UI for controls to change all the preferences. If you need to change a preference for which there is no UI, you will need to edit your preferences file, user.js. These instructions detail how to do this.
This file is read in by Mozilla when it loads your profile, so if you modify the file while Mozilla is running, your changes will not take effect until you restart Mozilla. If there is not already a user.js file in your profile directory, create it and then add the correct line or lines, which should have the form:
for on/off preferences. When you have finished editing, restart Mozilla.
When a page rendered in
full standards or
mode links to an external style
sheet (using <link>, @import, etc.), Mozilla
will load the style sheet only if it is served with a MIME type of
"text/css". Style sheets served with other MIME types, like text/plain,
application/x-pointplus, etc. will not be loaded.
To add the proper CSS MIME type to an Apache web servers, add
"text/css css" to the system mime.types file. Or if you can't do
that, add "
AddType text/css .css" to your .htaccess file.
