recently on a shared Windows 11 PC another user signed me out of Firefox and signed in with their Firefox account. For some reason this user kept my profile and now has access to my credit cards, passwords etc and this had synced to their other devices. So far I have not been able to log back in to Firefox on this PC. This is a security nightmare. Any thoughts on how I clean this up?
