Clearing the history works sometimes, but not others. Unpredictable when it will hang

This can be caused by clearing the cookies via Delete browsing, search and download history on Firefox.

  • Firefox/Tools > Options > Privacy > Firefox will: "Use custom settings for history" > [X] Clear history when Firefox closes > Settings
  • Firefox > History > Clear Recent History or Tools > Clear Recent History

Try to exclude the cookies to see if that helps.


Let all cookies expire when you close Firefox to remove unwanted cookies and keep the ones with an allow exception.
Make sure that you do not clear the "Site Preferences" as that will remove all exceptions.
