Logged out

That's strange. Did your browser update recently or crash unexpectedly? Sometimes that can log you out of sites. Also check if any extensions or security settings might be clearing cookies automatically.

I know for sure that extensions do not automatically clear cookies.

As for Firefox crashing, this browser tells me "Your tab has crashed" almost every day. I have a fairly old computer, so I think this happens because I try to open 6-7 tabs at the same time and because of this one or two of them "Crash".

Maybe there is some utility or setting in the browser with which I could check this, maybe there really is a problem in the browser and frequent tab crashes - is this some kind of error or a consequence of incorrect settings or something like that?

Yeah, me too. Today, when I started the browser, I was logged out of all my accounts, and I didn't do anything. I don't know what caused it; I thought it was just me

Same here. After 133.0.3 update. Every time I close and open firefox, all sites are logged off... (PS: It keep logged in before, I didn't changed anything, only firefox upgraded itself... So it is firefox 133.0.3 issue...)

This has happened to me too. Is there a new setting in firefox to prevent this? This has been a real POA. I'm running firefox 136.0.2 on Mac OS 15.3.2. This behavior started about a week and a half ago.
