Did you make manual changes to prefs?
gfx.direct2d.disabled: true gfx.direct2d.force-enabled: true keyword.URL: true (?; this pref is no longer used and should have been a string pref) layers.acceleration.disabled: true
You can cleanup the prefs to have a fresh start and delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
