You can try to disable hardware acceleration in Firefox.
- Settings -> General -> Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available" - https://support.mozilla.org/en-US/kb/performance-settings
Close and restart Firefox after modifying the setting to apply changes.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

You're welcome. Do you remember when and why you started using userChrome.css ? Was that to fix an issue with the address bar drop-down that you didn't like ?
