This article contains instructions to uninstall Firefox and remove it from your system. Make sure you complete the last step, removing the user profile data, if you wish to completely remove Firefox or perform a clean reinstall.
Note: You should set another default browser if you are not going to reinstall Firefox and it is currently the default [1]. You can use the information in this article as a general guide.
On Mac OS X
Drag the Firefox application to the Trash.
On Linux
Remove the firefox Installation directory, usually: /usr/lib/firefox-<version>. For example, if using Firefox 1.0 it would be: /usr/lib/firefox-1.0
On Windows
Exit Firefox completely, then:
- Open the Windows Control Panel and double-click Add/Remove Programs. Select "Mozilla Firefox <version>" in the list and click "Remove" to run the uninstaller. Even if this first step fails, as it may in some cases, continue on with the rest of the uninstall instructions.
- Delete the Firefox Installation directory, located here, by default: C:\Program files\Mozilla Firefox
- Delete the "Firefox" folder that contains temporary data ( *.mfl files, Cache and Updates) located here:
- Windows 2000/XP: C:\Documents and Settings\<username>\Local Settings\Application Data\Mozilla\Firefox
- Windows Vista: C:\Users\<username>\AppData\Local Data\Mozilla\Firefox
The above locations are hidden by default. Read this for help viewing hidden files and folders. Important: Make sure you delete the "Firefox" folder under Local Settings or Local Data. Deleting the wrong "Firefox" folder will remove your user profile data!
- If you installed the Quality Feedback Agent component (aka Talkback), open the %APPDATA%\Talkback\MozillaOrg\ folder and delete all "Firefox<somenumber>" folders found, for example, "Firefox10" "Firefox15" and "Firefox2".
- Windows XP/Vista: Delete all C:\WINDOWS\Prefetch\FIREFOX* files
- If necessary, remove the "Mozilla Firefox" shortcuts in the Windows Start -> Programs menu by right-clicking and deleting the entries. (This step should not be needed unless the Add/Remove Programs uninstaller in the first step failed.)
The Firefox uninstall will leave behind some Windows registry entries, which can be cleaned up using Windows regedit or a 3rd party registry cleaner. Note: registry editing is a potentially hazardous undertaking!.
You may also need to manually change some file associations or icons in your Windows "Folder Options -> File Types" even after setting a new default browser, as reported here.
Removing user profile data
This step is recommended if you had problems with Firefox and are now preparing for a "clean reinstall" or if you want to completely remove Firefox from your system. This will remove the Firefox user profile data, which includes bookmarks, passwords, cookies, preference settings and added extensions:
Back up your profile data so that you can restore it later, if you wish, then delete (or rename) the Firefox folder in the default profile path. This folder includes the "Profiles" subfolder and the files "profiles.ini" and "pluginreg.dat". In Windows XP, for example, go to "Start -> Run -> (type in) %APPDATA% -> click OK" to open the hidden Application Data folder, then open the "Mozilla" folder and delete (or rename) the "Firefox" folder.
Caution: Do not simply delete the profile folder that contains your user data, as doing so can result in a "profile in use" or "already running" message when you next attempt to run Firefox (bug 278860).
