Namely, the top left start button (normally, 'Firefox' or 'Aurora') as well as back navigation button seem to unpredictably change their background image/color in accordance to the websites's css properties.

Chosen solution

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.
