This issue can be caused by an extension that isn't working properly.

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 or otherwise make changes.

Thank you for your response. The error does not happen in safe mode. But, I don't understand what I need to do to solve the problem when I'm not in safe mode. Thanks for your help.

I just disabled my GoodSearch app and it solved the problem. Bummer that Firefox has made me disable 3 apps in recent memory. Thinking of using a different web browser. Thanks.
