That could be a problem with the theme that you use. You can check if there is an update.

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

• Make sure that you do not exceed the maximum size of 1 MB

Hi, it doesn't seem to be needed now. Eg - Settings for privacy, browsing history and do-not-track.

There is no OK (Save) button on the about:preferences page like you had in the previously used standalone Options/Preferences window when browser.preferences.instantApply was false (default on Windows). Changes are applied immediately as you can see if you open the about:config page in a second window and have them both visible.

The prefs toggled on the about:preferences#advanced under accessibility settings are among the first accessibility prefs that appear at the top of the about:config page.
