I have updated my firefox to version 15.0. After this I have the effect that at some unspecified time during use many of the functions stop working. Menu's do not open, download links do not work anymore and so on. Opening new tab's or windows still works. Links on pages partly work partly not. Copy and paste does not work anymore on webpages. It takes ending the firefox process and restarting to correct the issue until it happens again. I have those effects on totally different webpages. At this time it happens every time after I start Firefox but not right away. Firefox first works for some time and then it suddenly doesn't anymore without me having done anything special

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, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  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.

Start Firefox in Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
