firefox 133.03 installed without permission and deleted profile, backup, address and paswords. even went as far as deleting backup on different folds

firefox update 133.03 has wiped my harddrive of all profiles for the browser including backups even backup that were in different folders. How can I roll back now. I even tried to use a restore point from the day before and it did not help.

That is strange. Firefox normally just updates the installation it finds.

Did you by any chance switch between the standard Mozilla build and a special build such as the Windows store version or the PortableApps version?

Also, I know it's rare, but is it possible you are signed in under a different Windows user profile?
