Hi there! I understand how frustrating it can be when the latest update causes issues. You're not alone in experiencing this with version 116 on Windows 10. It seems like some compatibility hiccups might be causing problems with Google apps and other Windows 10 apps. One thing you can try is to refresh Firefox. This usually helps resolve unexpected issues. Go to the Help menu, select "Troubleshooting Information," and click on the "Refresh Firefox" button. This will keep your important data while giving Firefox a fresh start. Give it a shot and see if it improves your situation. Let us know how it goes, and we're here to help further if needed!

This is likely a problem with the AdBlocker Ultimate extension as there have been similar reports.
