Honestly, I barely understand how Firefox's cookie protection works anymore. It used to have the simple option to block third party cookies that I had running all day and felt good with. That was until they started becoming necessary in certain scenarios (I can't even remember the details of what that was).
And then these days I have no idea if I can just accept a website's advertising cookies and expect Firefox to block them anyways, or if clicking on such a button would disable the browser's tracking protection.
