If there are problems with updating then best is to download the full version of the Firefox installer.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile data are stored in the Firefox Profile Folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.

You should also update your plugins

Ok, there are a bunch of other problems you have here, so let's get all of them resolved Smiley Happy

Firefox, restart your PC.


Second, update Firefox to 18.0. Update Firefox to the latest version

Then, follow the steps at Websites say that Firefox is outdated or incompatible even though it's the latest version

After that, update your plugins. https://www.mozilla.org/plugincheck/

Finally, Reset Firefox. Refresh Firefox - reset add-ons and settings
