When I try to open Firefox, it sits in the taskbar like it is open, but I cannot access the window for it when I click on it. It was working fine 2 days ago, and now it is broken. I have done a system restore to a previous time when it was working, and gotten rid of any programs that may have been causing issues. What can I do to try and fix since I cannot get access to the Firefox menus to do anything suggested on the support site?

Hello,

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thank you.
