After downloading FF 20.0.1, I can no longer open multiple FF windows; tabs still work.

I upgraded directly from version 18.0, and now I can't open more than one Firefox window. Like I said, all my tab functions are still working, but I'd like to be able to open multiple windows at times. I had the same problem with version 19.0, which is why I rolled back to 18.0. Any ideas?

I don't have this problem on windows. I just right click the link, then click 'open in new window', and it works fine

Hello grumman061, Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.

(If you're not using it, switch to the Default theme.)

  • You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
  • Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.

Once you get the pop-up, just select "'Start in Safe Mode"

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 for that.

To exit the 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 other users who have the same problem.

Thank you.

Thank you, ideato! I found the culprit among one of my add-ons.
