Can't Sign-Out of Firefox Account
I'm trying to sign-in to my Firefox account, but it won't let me as I'm still signed-in on another device. The other device is my old SSD which failed and can't access anymore. How do I sign-out of the old SSD so I can get access to my Firefox account on my new SSD?
Tried via the website and keeps saying 'Primary account email required for sign-in', which I only have one email address linked to that account that I know of. I had this error before when changing PC's and by signing out of the old PC it resolved that error, which is the same issue I'm in now but still log-in on a failed SSD.
