Intelligent Tracking Prevention
I am surprised how complicated it is, they even use machine learning. It will look like a bug to developers when the third-party cookies will suddenly stop working without obvious reason.Why don't just block third party cookies except where it is enable by the user? I think 100% of the sites I visit use third-party cookies only for tracking.And of course this is not enough. Using a combination of an IP address and browser fingerprint allows tracking a user without any cookies.And websites can still track users if they use a redirect through an analytics website (when a user visits a site for the first time he is redirected to an analytics domain, that redirects the user back adding an identifier to URL).
