Firefox now opens a new window, rather than a new tab

Firefox now opens a new window, rather than a new tab when I click on a bookmark or the +, or when I start a new download, regardless of Tabs settings in the Options General page. This is different from original behavior, and I have no idea what happened. How do I change back to Tabs rather than window?

That is not normal behavior.

You can 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 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 Troubleshoot Mode start window
