Firefox crashes on opening with immediate werfault.exe. I upgraded from Win 7 to Win 10 32-bit with upgrade that preserved files & programs. Everything works but firefox. I've tried uninstall/install, uninstall & extensive removal of all remaining mozilla/firefox files and cleaned registry with regedit all relevant instances of firefox. then reinstalled but still failed in the same way.

Turned off all non microsoft services with msconfig. No help

Tried to use administrator account and got the system so that I could not log in. I had to refresh windows/ keep files.

After that reinstallation of win 10, firefox works.

I now have to reinstall 4 pages of apps.

But at least firefox works (for now).

Thanks for your attemtion.

I wish the original problem could have been identified.

That was very good work. Well Done. Please flag your last post as Solved Problem as this can help others with similar problems.


Back up and restore information in Firefox profiles.{web link} I use an add-on that makes backups of my user profile, Just In Case. Unfortunately, it is not compatible with the current Firefox.

Every now and then, open the profile folder and create a copy of the current profile as is to another location on your hard drive. This way you will have a backup.

If you do this each day, you will not lose much data. This should be done with Firefox Closed.

Note: In case you need to restore from these backups, you may need to overwrite old or corrupted files.
