Every time I close Firefox (doesn't matter how I close it), I get TWO pop-ups that say "Firefox has stopped working"

Every time I close Firefox, I get TWO pop-ups, the second appearing right after I close the first. They both say "Firefox has stopped working".

It doesn't matter if I close Firefox by the "X" in the corner, or click File ¦ Exit, or if I just close every tab (closing the last tab closes Firefox).

I tried it with Add-Ons disabled. Same thing.

I did a Refresh of Firefox. Same thing.

I have it on several other machines (and several operating systems), this is the only one it does this on, yet I have the same setup, the same add-ins, etc. This one is running Windows 7.

Please advise.

Thanks!

Chosen solution

  • Replaced the Video drivers (Intel AND Nvidia) as specified above. No joy.
  • Uninstalled and deleted folder as specified above. No joy.

--- On my own, closed one icon at a time from icon tray, then opening and closing firefox with each closure. Eventually found that LastPass for Applications was causing the crashes. Uninstalled same. No more crashes.

Note: Affected PC is Win7 corporate box, and they do not always install updates in a timely manner. On all my personal boxes (all Win 10), LastPass for Applications does not cause this issue.

Try this and see if improves anything since have tried Safe Mode and Refresh

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0 with a Full Version Installer https://www.mozilla.org/firefox/all/
