  2. Click the Firefox menu Fx89menuButton and select Exit.Click the Firefox menu at the top of the screen and select Quit Firefox.Click the Firefox menu Fx89menuButton and select Quit.
    • Make sure Firefox is not running at this point.
  1. Within your profile folder, rename these files:
    • Rename formhistory.sqlite to formhistory.sqlite.bak.
