This issue can be caused by an extension that isn't working properly.

Do you have any AVG extensions or toolbars installed?

  • Tools > Add-ons > Extensions

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).
