I recently got a prompt to get the latest version of Firefox 85.01. After installing it (there were some glitches in doing so) it erased all of my settings, my bookmarks, and saved passwords. I have lost so much from it literally broke my heart. I had a huge library of bookmarks that are all gone. I spend hours going through each website I have to log into and either find the old password or create a new one. Your upgrade has been one colossal headache.

Is 85.01 a valid upgrade or was I scammed and being scammed to get all my passwords?

If it is valid upgrade, why would you delete all of my setting and data?

Very angry!

Look on your desktop. Do you see a folder called; Old Firefox? Look inside. Look for the folder with the latest creation date.
