This issue can be caused by the McAfee Site Advisor extension

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). 

    Don't make any changes on the Safe mode start window.
