I thought I just needed to sync my account ( three bars > user name > sync now) and sign out before resetting my computer. After doing so I thought by signing in it would recover my bookmarks and passwords, etc. I did NOT do the proper way: https://support.mozilla.org/en-US/kb/switching-devices which I realized after performing the reset. Am I completely SOL? Or is there a way to recover these - I really hope there is I had a lot of bookmarks. Thank you for your time and support!
