I set up Firefox for deleting cookies when the session is closed, as recommended by privacyguides and arkenfox. I add sites for which I want to keep the login to the exceptions. I noticed that, by doing so, I also allow the site for using cross-site cookies (see attached screenshot). However, I would like to keep blocking cross-site cookies, I just need the site’s cookies to keep the login. Am I doing something wrong? I’m afraid that I’m bypassing total cookie protection.
