Whenever I drag a tab to another window in Firefox, the first window will hide all but the most recent tab. The only way to unhide them is to open a new tab. Is there a way to turn this off? I can't figure out what's causing it.

Chosen solution

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
