It sounds like you're looking for Privacy Badger: it uses heuristics to block requests and cookies from third-party sites based on their behaviour in your browser. https://www.eff.org/privacybadger https://www.eff.org/privacybadger The basic rule is that if more than one first-party site tries to connect to the same third-party, that third-party could be tracking you and will be blocked.
