Start Firefox in Diagnose Firefox issues using Troubleshoot 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).

Try to disable hardware acceleration.

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
