Out of the blue all my bookmarks and passwords disappeared, When I follow your instructions there are no backups in your files. Toolbar is missing and right clicking shows a check mark but no toolbar, I have already switched to Chrome and guess what they have all my bookmarks but no passwords. Passwords are no problem I saved them more so than you backed up your files. I guess it was an update, I don't know. I am 85 years old and have used Firefox a number of those years, probably longer than whoever reads this has has been with us.I guess you know which path I'll be taking from now on. Just thought I would let you know. PS and there will not be anymore automatic updating I'll do it myself I trust me. Stick a fork in me I'm done !
