When I click on a dropdown the settings automatically open in a new tab. For instance when logging into something and choosing my password and/or username from a dropdown, when I click on my choice a new tab suddenly opens with the settings menu - specifically the autofill thru permissions area in the "privacy and security" submenu. Just started doing this randomly the other day so I rebooted the computer and that fixed the problem, but its now started doing it again. Please help?

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

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