Firefox is my browser of choice. It is faster than Internet Explorer and I prefer its user interface over Google Chrome. Like all programs, sometimes files get corrupted. If your Firefox browser is unable to load, the fix is easy enough.

  • Make a copy of the user’s profile files. These can be found in c:\Users\<user name>\AppData\Local\Mozilla and c:\Users\<user name>\Roaming\Mozilla or c:\Documents and Settings\<user name>\Local Settings\Application Data\Mozilla and c:\Documents and Settings\<user name>\Application Data\Mozilla.
  • Uninstall Firefox, make sure you delete all user profiles.
  • To be sure, delete the two folders above (but not their copies). Then delete the c:\Program Files\Mozilla Firefox\ folder or c:\Program Files (x86)\Mozilla Firefox\ folder.
  • Reinstall Firefox.
  • The installation process will create a new user profile. Quite Firefox. Then go back to the folders in the first step and delete the new user profile folders. Then rename the copy user profile to the above names. This will return all your plugins and preferences.
