Forum der Gemeinschaft Firefox

I am using firefox on linux since ~10 years. Currently running latest FF on Kubuntu. I always had setting set to forget all cookies and session details except of search history on exit.

Since approx 2-3 weeks (latest update?) those settings don't work. FF remembers everything regardless of settings I chose.

Does anyone have idea why this is happening now and how to fix it?

Sometimes, after restarts, FF forgets every site I'm logged into. Open tabs persist, the login sessions do not. I have no better observation of when this happens, I'm afraid - it's not every time. Because of this it's very hard to reproduce reliably - over the past 2 weeks, it didn't happen and now it was 2 days in a row. "Clear cookies and site data" is definitely off. I have no extensions apart from Dark Reader and uBlock. Because my daily work requires me to use a dozen sites I have to log into, all using 2FA, this is incredibly annoying. I have also completely reset my profile, which did help for a while but then it started again - so I'm thinking the profile reset was more of a coincidence than actual causality.
