Firefox sometimes continuously adds tabs for the same site I am using. Every time I X out of one, another one pops up. This multiplies alarmingly fast. I have Windows 10.

Could that be about this issue?

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
