Firefox Community Forum

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

I recently noticed that my Microsoft account remains active after I sign out if I press the back button. All my personal and account information is still displayed, indicating that the account is still signed in. I even tried clearing all browsing data and history, but that didn't resolve the issue. This doesn't happen with my Gmail account, nor when I access my Microsoft account using Edge or Chrome.

I understand that closing the browser likely signs me out, but I have no way to confirm that unless I check for active devices in my account settings. Can you explain why this timeout issue occurs? It seems odd, especially since Mozilla prioritizes security and privacy.
