What do you mean; "always reverts back" ?

What version were you using? What version is it becoming?

As to your data, Look on your desktop. Do you see a folder called; Old Firefox?

Thanks, I now have back up and running.

Glad to help. Safe Surfing.


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.
