What's your Firefox version?

Are you logged in as an administrator?

Try to reinstall Firefox as a normal user and make sure to delete the Firefox program folder if it is still present.

  • (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
  • (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"

You can find the full version of the current Firefox release (65.0) in all languages and all operating systems here:
