OK so this just happened to me. I have a Mozilla account since I was using their Monitor and VPN service. Last year I canceled those subscriptions because it wasn’t really working for me. Today I start up Firefox and I was signed in to my Mozilla account! I never signed in through Firefox. They’re sus now.
You must log in or # to comment.
Honestly, they probably store certain config in the local/mozilla folders or whatever and Firefox also does and thus was signed in. Though, this is all speculation.
Are you using Firefox Sync with the same e-mail address? I believe, that all gets put into the same account system.
No I do not use any Sync functionality. I purposely don’t sync my browser because I don’t want any company to know my bookmarks.
Firefox Sync is end-to-end-encrypted. Mozilla cannot see your synced data.
Either way, I have no idea how this is supposed to happen without you entering your credentials into Firefox at some point. Even if Mozilla wanted to be sus, they couldn’t just guess which account is yours.
Check your passkeys. You might still have one in the OS credential manager.
I had a weird thing, I abandoned a reddit account after a 3 day ban over a month back. I cleared the cookies, presumed it was logged out. Cleared all cookies, cache, history, all of that like 20 times, and after clicking on a few reddit posts as search results to get links to streaming shows, I noticed it had me logged in somehow.
I never even set it up to automatically log me in, or even fill in my username. I had to type in my username and then select my password from the manager by hand.
How is it it apparently kept me logged in for a month, or at least every time I found a reddit thread on a search engine and clicked on it? Am I hacked?
