My system installed Firefox Browser Version 78.0.2 overnight. This morning my Firefox display is different. I am missing the header bar that contained a choice between opening a new window or a new tab, bookmarks, Firefox support ( question mark inside a circle), etc. Further all my bookmarks, logins & passwords, open tabs, history, add-on, and preferences ARE MISSING. Prior to this update I did not have a Firefox account so the SYNC procedure recommended in the open Firefox window DID NOT RECOVER ANYTHING. How do I get back my missing information and return my Firefox screen to its previous configuration?

Hi, try to enter about:profiles in the URL bar. How many profiles do you have there?

Also,

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