Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

cor-el, I closed all the Tab extentions and restarted. One of those Tabs was causing the problem. I now have the Tab Quick Switch back. Thanks for the help.
