Downloading and Installing

System Requirements

Before installing, make sure your computer meets the system requirements.

Downloading Firefox 2

Mozilla provides Firefox 2 for Windows, Linux, and Mac OS X in a variety of languages. You can get the latest version of Firefox 2 here. For builds for other systems and languages not provided by Mozilla.org, see the Contributed Builds section at the end of this document.

Installing Firefox 2

Please note that installing Firefox 2 will overwrite your existing installation of Firefox. You won't lose any of your bookmarks or browsing history, but some of your extensions and other add-ons might not work until updates for them are made available.

Removing Firefox 2

You can remove Firefox 2 through the Control Panel in the Start Menu on Windows, by removing the Firefox application on OS X, or by removing the firefox folder on Linux.

Removing Firefox 2 won't remove your bookmarks, web browsing history, extensions or other add-ons. This data is stored in your profile folder, which is located in one of the following locations depending on your operating system:

Windows Vista	Users<UserName>AppDataRoamingMozillaFirefox
Windows 2000, XP, Server 2003	Documents and Settings<UserName>Application DataMozillaFirefox
Windows NT	WINNTProfiles<UserName>Application DataMozillaFirefox
Windows 98, ME	WindowsApplication DataMozillaFirefox
Mac OS X	~/Library/Application Support/Firefox
Linux and Unix systems	~/.mozilla/firefox

Any version of Firefox that you install after removing Firefox 2 will continue to use the data from this profile folder.

Extensions and Themes

Extensions installed under Firefox 1.5 may be incompatible and/or require updates to work with Firefox 2. Please report any issues to the maintainer of the extension. When you install Firefox 2 all of your Extensions and Themes will be disabled until Firefox 2 determines that either a) they are compatible with the Firefox 2 release or b) there are newer versions available that are compatible.

Known Issues

This list covers some of the known problems with Firefox 2. Please read this before reporting any new bugs.

All Systems

Some firewall software may silently block Firefox from running. This often happens immediately after Firefox has been installed or updated from a previous version. There are configuration instructions available for most popular firewall programs to help you ensure that Firefox is allowed to connect to the Internet.
Dictionaries for several locales can't be packaged with the builds, and must be manually downloaded by right-clicking in a text area and selecting 'Add Dictionaries...' from the shortcut menu. New dictionaries are regularly being added to Mozilla Add-ons, so if you don't see the particular dictionary you need, check back later.
Access key definitions provided by web pages can now be triggered using Alt+Shift+key on Windows, Ctrl+key on Mac OS X, and Ctrl+Shift+key on Unix.
The Session Restore functionality provided in Firefox 2 will restore connections to services which use session cookies to maintain login state such as GMail. It is recommended that users with concerns about the privacy implications of this behavior change the value of browser.sessionstore.resume_from_crash to false.
The option for 'Shrink to fit' has been removed in Firefox 2. If you wish to change this from the value you had set in your previous version of Firefox, change the value of browser.enable_automatic_image_resizing.
Software Update will not work if Firefox is installed to a location on your disk to which you do not have write access, since Software Update needs to replace or create files in this location.
Some financial institutions use port 563 for secure logins, which results in an error message. If you encounter this error, make sure that network.security.ports.banned.override includes 563 in the comma-separated list of banned network ports to override.
The CSS 'clear' element is sometimes ignored on pages with elements that use the 'float' element. There is a workaround available for web developers.
After updating, add-ons may become disabled and enter an endless loop of trying to update themselves. This can be fixed by removing some files from your profile directory.
Removing the 'area' element from image maps will result in the entire map disappearing.

Windows & Windows Vista

On Vista, Java applets will not work unless Firefox is 'Run as administrator' at least once after being updated.
The Java Console extension that came with Java SE 6.0u1 (J2SE6.0.01) is incompatible with Firefox as reported in Bugzilla. Java should work as expected, but the menu item 'Java Console' will not be available in the Tools menu. This issue has been fixed in Java SE 6.0u2 (J2SE6.0.02) and later versions and is available for download from the Java website.
Clicking links in some applications (e.g. some instant messaging programs) might not open them in Firefox, even if you have set it as your default browser. To workaround this problem, go to Start -> Default Programs -> Set default programs for this computer, expand custom, select the radio button next to the app you want to set as the system wide default app (e.g. Firefox, etc.), and apply.
A Windows Media Player (WMP) plugin is not provided with Windows Vista. As a workaround, in order to view Windows Media content, you can follow these instructions. Note that after installing you may have to get a security update and apply it before you can see the content in the browser.
Vista Parental Controls are not completely honored. In particular, file downloads do not honor Vista's parental control settings. This will be addressed in an upcoming Firefox release.
When migrating from Internet Explorer 7 to Firefox, cookies and saved form history are not imported.
Use of the install-global-extension and install-global-theme command line arguments have been restricted to only allow installing add-ons that are on local disks or mapped drives. Installing from a network share directly will no longer succeed.

Mac OS X

On OS X 10.5 (Leopard), there are known problems with some media plugins as well as Add-ons that contain binary components. Also, the tabs in Preferences > Advanced will not render properly.
The 'Close Other Tabs' action on the shortcut menu of a tab can fail with an error when more than 20 tabs are open.
Some users have reported problems viewing Macromedia Flash content on Intel Mac computers. To work around this problem, users can remove or move the PowerPC version of 'Flash Player Enabler.plugin from /Library/Internet Plug-Ins.
After installing a new plug-in, Firefox may continue to display information for the older version of the plug-in in about:plugins. If this happens, quit Firefox, delete the 'pluginreg.dat' file from your profile folder, and relaunch Firefox.
Java does not run on Intel Core processors under Rosetta.
There is no Talkback on Intel-based Macs when running natively or under Rosetta. The Apple Crash report program should launch in the event of application crashes.
