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

Try to rename (or delete) the xulstore.json file in the Firefox profile folder.
You can use this button to go to the currently used Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
