I am trying to retrieve my passwords and bookmarks on my PC but every time I try to log in the program says "NOT RESPONDING ". I did manage to do it about a week ago but they have gone again.

If you haven't already, could you try starting Firefox in its Troubleshoot Mode? In that mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to simplify the environment and hopefully bypass problelsm.

If Firefox is running:

You can restart Firefox in Troubleshoot Mode using either:

  • "3-bar" menu button > Help > Troubleshoot Mode...
  • Help menu (Alt+H) > Troubleshoot Mode...

and OK the restart. A small dialog should appear. Click the Open button.

If Firefox is not running:

Hold down the Shift key when starting Firefox. A small dialog should appear. Click the Open button.

Note: Don't use the Refresh without first reviewing this article to understand what will be deleted: Refresh Firefox - reset add-ons and settings.

Any improvement?
