Downloading and Installing
Before installing, make sure your computer meets the system requirements.
Mozilla.org provides Bon Echo for Windows, Linux, and Mac OS X in a variety of languages. To get the latest version of Bon Echo, browse the FTP site. For builds for other systems and languages not provided by Mozilla.org, see the Contributed Builds section at the end of this document.
Once you have downloaded Bon Echo, follow these instructions to install:
Double click the Bon Echo Setup Alpha 2.exe installer to start the install.
Mac OS X
Double click the Bon Echo Alpha 2.dmg Disk Image to uncompress and mount it. Your browser may have already done this for you. Double click the BonEcho Disk Image to open it in Finder and drag the Bon Echo application onto your hard disk. Do not double click the icon in the disk image! Be sure to drag the Bon Echo application out of the disk image and onto your Hard Disk before running it. Drag the icon to your Dock if you want it to appear there.
Extract the tarball and run ./firefox:
tar -xzvf bonecho-alpha2.tar.gz
Extract the compressed archive and run firefox
Uninstalling Bon Echo Alpha 2
To uninstall Bon Echo Alpha 2, follow these instructions:
From the Start menu, choose Control Panel. When the Control Panel appears, double click Add/Remove Programs. Find "Bon Echo (2.0a2)" in the list and click Remove to uninstall.
Mac OS X
Drag the BonEcho application to the Trash.
Remove the firefox folder.
These instructions leave your profile in place in case you install Firefox again in the future. If you wish to remove your profile folder, remove the location described below in the "Profile Folder" section. Note that by doing this you are destroying all of your downloaded Extensions and Themes, Bookmarks, saved passwords, settings and other information and should you decide to use Firefox again you will be starting with a clean profile.
Bon Echo stores your user data in one of the following locations:
|Windows 2000, XP||Documents and Settings\<UserName>\Application Data\Mozilla\Firefox|
|Windows NT||WINNT\Profiles\<UserName>\Application Data\Mozilla\Firefox|
|Windows 98, ME||Windows\Application Data\Mozilla\Firefox|
|Mac OS X||~/Library/Application Support/Firefox|
|Linux and Unix systems||~/.mozilla/firefox|
Extensions and Themes
Extensions installed under Firefox 1.5 may be incompatible and/or require updates to work with Bon Echo Alpha 2. Please report any issues to the maintainer of the extension. When you install Bon Echo Alpha 2 all of your Extensions and Themes may be disabled until Bon Echo Alpha 2 determines that either a) they are compatible with the Bon Echo Alpha 2 release or b) there are newer versions available that are compatible.
History and Bookmarks
The new history and bookmark system used in Bon Echo Alpha 1 has been removed in Bon Echo Alpha 2. You will need to follow these steps if you are migrating a profile from Bon Echo Alpha 1.
This list covers some of the known problems with Bon Echo Alpha 2. Please read this before reporting any new bugs, and watch it regularly (we'll update it as new bugs are found in the release).
History and Bookmarks:
- The new history and bookmark system used in Bon Echo Alpha 1 has been removed in Bon Echo Alpha 2. You will need to follow these steps if you are migrating a profile from Bon Echo Alpha 1.
- When moving to Bon Echo Alpha 2 from an earlier version of Firefox, some of your Extensions and Themes may be disabled. This is not an issue, but it may appear to be one (hence its listing here). For rationale, see "Extension and Themes" above.
Inline Spell Check:
- There is a known bug that causes lines that contain non-standard ASCII characters and misspelled words to disappear.
Mac OS X
- If you browse to a site that issues a SSL certificate which doesn't match the domain name of the site, and then choose to view that certificate, a blank dialog will be presented and hang the browser. A workaround is to change security.warn_entering_secure to be false in about:config or to not view the certificate. More details in bug 337646.
Linux and Unix systems
Web Page Rendering
Poorly designed or incompatible Extensions can cause problems with your
browser, including making it crash, slowing down page display, etc. If
you encounter strange problems relating to parts of the browser no
longer working, the browser not starting, windows with strange or
distorted appearance, degraded performance, etc, you may be suffering
from Extension or Theme trouble. Restart the browser in Safe Mode. On
Windows, start using the "Safe Mode" shortcut created in your Start
menu or by running
firefox.exe -safe-mode. On Linux, start with
./firefox -safe-modeand on Mac OS X, run:
When started in Safe Mode all extensions are disabled and the Default theme is used. Disable the Extension/Theme that is causing trouble and then start normally.
If you uninstall an extension that is installed with your user profile (i.e. you installed it from a web page) and then wish to install it for all user profiles using the -install-global-extension command line flag, you must restart the browser once to cleanse the profile extensions datasource of traces of that extension before installing with the switch. If you do not do this you may end up with a jammed entry in the Extensions list and will be unable to install the extension globally.
If you encounter strange problems relating to bookmarks, downloads, window placement, toolbars, history, or other settings, it is recommended that you try creating a new profile and attempting to reproduce the problem before filing bugs. Create a new profile by running Firefox with the -P command line argument, choose the "Manage Profiles" button and then choose "Create Profile...". Migrate your settings files (Bookmarks, Saved Passwords, etc) over one by one, checking each time to see if the problems resurface. If you do find a particular profile data file is causing a problem, file a bug and attach the file.
