probably dupe of wontfixed 349680
I manually flipped the old pref (network.cookie.cookieBehavior) from the default 0 to the "no 3rd party" setting 1 which is all the UI used to do (no functionality was removed from the product, it was just removed from the UI). In both cases I got exactly the same set of cookies: two from seb.se and one from instandia.net In any case that's each site simply setting its own cookies, you have not explained or demonstrated "passing of cookie details". Not sure what that would mean, but there is absolutely no way to prevent two servers sharing data if they want to: they could do it by loading iframe urls with query parameters, redirects (which this site obviously uses given sebank.se ends up on seb.se), or do it on the back end completely invisible to the browser.
