Suddenly I cannot close firefox tabs, I opened some tabs and click red X button but nothing happened. I can click menu, it run well, download, it run well, back button it works, bookmark button, it works. But one thing I can't do, it's closing tabs, all tabs.

Can you close a tab with a middle-click or the Ctrl+W shortcut?

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
