Every time I shut down my PC, Firefox starts up on boot having signed out out my account, signed out of all websites and losing all site data including passwords. I have had this problem for more than a week if not two weeks at this point, and I've asked for help and all I have heard is to make sure Firefox is set to remember your history. I've checked this setting, fixed it and hasn't worked to solve anything. I need help urgently because I'm getting super frustrated by how buggy this browser has become.
