HELP! Firefox keeps randomly switching windows.

more options

Every time I open a new window link from a current window, the new window will pop up like normal.

But after I click on anything inside the new window, Firefox randomly switches to the previous window and I have to reclick the new window to get it back.

How do I fix this? I don't want it to keep switching back to the old window when I've already opened a new one.

I'm using the latest Firefox build 23.0.1, fresh install with Windows 7 64 bit.

Hello,

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.

Sounds like a bug in the Flash Player plugin's Protected Mode. Check out the following thread for a further description and known workarounds: Opening New Windows and Shockwave Flash.
