Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: This will cause you to lose any Extensions and some Preferences.

  • Open websites will not be saved in Firefox versions lower than 25.

To Reset Firefox do the following:


  1. Click the menu button New Fx Menu, click help Help-29 and select Troubleshooting Information.Now, a new tab containing your troubleshooting information should open.
  2. At the top right corner of the page, you should see a button that says "Reset Firefox"Button reset. Click on it.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.
