When I have two or more FF windows open, FF randomly and without warning switches from onen window to another. I'm running V22. Had the same problem with V21.
When I have multiple windows open (not tabs, but windows), FF spontaneously switches from one window to another. I haven't moved my mouse/clicked on anything to bring the other window up; it just happens, very randomly, and during virtually every FF session. I'm running FF V.22, but had this same problem w/FF V.21.
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.
