This is a rough summary of Privacy Badger's internal logic for blocking trackers. At the moment, "tracker" == "third-party cookie from a site that tracks you on multiple first-party origins." I am in the process of adding support for other non-cookie tracker types (local storage, etags, cache hits, etc.).
Privacy Badger uses a (relatively-simple) heuristic algorithm for deciding whether a third-party is tracking you. When Privacy Badger sees a third-party request on a website, it checks:
In addition, Privacy Badger will block third-party cookies from a domain if any of its parent domains have been blocked or cookie-blocked.
Note that users can manually set domains to be unblocked (green), cookie-blocked (yellow), or red (blocked). These choices always override the heuristic blocker.
By default, Privacy Badger sends the Do Not Track header on all requests. It also clears the referer for all requests that are cookie-blocked.
The current maintainers of this project are Cooper Quintin (cjq at eff dot org) and Noah Swartz (noah at eff dot org). There is also a mailing list to discuss Privacy Badger development for both Firefox and Chrome.
