Uninstall Firefox

Firefox logoThere are times when you might want to uninstall Firefox. For instance, you might want to clean up your machine and do a clean reinstall without all the Firefox addons for security reasons. You might even have become enamoured of the apparently all-singing, all-dancing Internet Explorer 8 (although that’s doubtful), or you may have defected into Opera territory.

Whatever the reason, the how to uninstall Firefox instructions from the Mozillazine site are summarized below.

  • Linux Users – Remove the firefox Installation directory, usually: /usr/lib/firefox-. For example, if using Firefox 3.0 it would be: /usr/lib/firefox-3.0
  • Mac Users – Drag the Firefox application to the Trash. Firefox also has a .plist file at ~/Library/Preferences/org.mozilla.firefox.plist you may wish to remove
  • Windows Vista – Go to “Programs -> Programs and Features”, select Mozilla Firefox and click click Uninstall. Then delete the Firefox Installation directory, located here, by default: C:\Program files\Mozilla Firefox
  • Windows XP or earlier – Double-click “Add or Remove Programs” Select “Mozilla Firefox ” in the list of installed programs and click “Remove” to run the uninstaller. Windows users should check out the Mozillazine page to find out how to remove orphan files and remnan folders that will undoubtedly remain on your machine after the supposed uninstall.

Uninstall Firefox

If you’re planning a clean reinstall, then you should also delete all the user data (although you might want to save or export your bookmarks file first). This step will become an option for Firefox 3 uninstall.

To get rid of the user data delete (or rename) the Firefox folder in the default profile path (or move it to a backup location). You must remove the Firefox folder and all of its contents including “profiles.ini” otherwise you’ll get an error when you try to run the reinstalled Firefox.
