Tab menu freezes; I can't click between tabs

Tabs in the tab bar randomly, suddenly can't be interacted with by mouse/trackpad pointer, sometimes even just the one and only tab in a window won't close when clicking on the "X." The keyboard commands to cycle between tabs and close tabs still work, but this is frustrating nevertheless. I've tried disabling all the add-ons I added in the month or two before the problem started. I refreshed Firefox, but once I added my add-ons back in, the problem persisted.

What else can I try to fix this? Any input would be appreciated.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
