Firefox linux does not clean cookies on exit as selected in settings
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?

It's a good catch.
Which version of Firefox are you using?
I always checked "Always use private browsing mode" in History so cookies and site data are deleted after closing Firefox.
Mizilla firefox debian package mozilla-deb-1.0 V 150.0.1 (64-bit)
Hey, yeah that sounds really annoying 😅 I’ve been on Linux + Firefox for years too, so I kinda get what you mean — you set it to wipe everything on exit, but it just keeps remembering sessions like nothing changed. I faced something similar a while back after an update. In my case, it turned out an extension was overriding cookie behavior. Also, sometimes Firefox creates a weird new profile or messes with prefs. What worked for me:
Disable all extensions and test once
Check about:config for anything related to cookies/sessionstore
Try a fresh profile just to confirm it’s not config corruption
.
Did you recently install any new add-ons or tweak privacy settings?
Hi,
Could you please check this in a new Firefox profile? It should be enough to sign in on any website, exit Firefox, reopen it and see if you are still signed in.
