You can try to disable hardware acceleration in Firefox.
- Options/Preferences -> General: Performance
remove checkmark: [ ] "Use recommended performance settings"
remove checkmark: [ ] "Use hardware acceleration when available"
Close and restart Firefox after modifying the setting for changes to take effect.
You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
