I-Firefox Community Forum

Hello Firefox Support Team,

I’m writing to report an ongoing issue I’ve been experiencing with Firefox over the past few months.

Within the last four months, Firefox has logged me out of every account I was signed into on three separate occasions. Each time this happens, all saved sessions are cleared and I have to sign back into every service again manually.

I haven’t intentionally cleared cookies, site data, or browsing history, and I’m not using private browsing when this occurs. This behavior is disruptive and I’m concerned there may be a settings issue, bug, or conflict causing Firefox to remove my sign-in data unexpectedly.

Could you please advise what might be causing this and what steps I can take to prevent it from happening again? I’m happy to provide additional details such as my operating system, Firefox version, or troubleshooting steps already attempted if needed.

Thank you for your time and support.

Best regards, Luka

A leak was detected on my account then Mozilla locked it. Every passwords were changed as I still got an "Email just returned" error upon trying to sign in, and now I end up with an "Unexpected error".

And to make sure that this has nothing to do with the plugins I have on my pc installation, I tried signing in on mobile phone as well. Same issue.
