My browser was compromised about 6 months ago. I sold that computer about 4 months ago. I never changed my FireFox Sync account password. Someone made purchases on my target account, paypal account, and ebay account. This morning, my microsoft account. They are all completely separate user accounts with different emails attached to them. They also tried compromising my G2A account, but I had no billing information saved with them. Again, these are all different user names and passwords. All of my devices and computers are shut off when the hacker tries compromising my accounts again, around 3AM eastern time. I've changed my password already, is there a way to sign out of all current devices and remove my passwords from those devices? I assume not, what else can I do in this situation other than delete account and change passwords?
