Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window

Go to your add-ons page and disable some of your add-ons. Then restart. If there is still a problem, disable more of them. Once the problem is gone, you will know what group the problem is in.
