All sites I was logged into are gone.
Since updating my laptop, all the accounts I was signed in on are gone. None of my passwords are saved in settings, I even tried to restore my backup. For some of these sites, my login was with an old email that I no longer have access to.

In the event that the passwords information is lost, you should record all information in a separate text file somewhere else on your hard drive, or written down. You can easily copy and paste if you need to do so. If you are concerned about someone else looking at that file, you can compress it using a password.
Look on your desktop. Do you see a folder called; Old Firefox?
