I use privacy badger, and unless I'm mistaken, it doesn't use a list to block content, it just blocks any 3rd party request that send cookie information. Why are we relying on a list?
That approach might not be enough: https://github.com/jspenguin2017/uBlockProtector/issues/95 Edit: the linked issue is regard "instart" which seems to exploit a Chromium flaw that allows it to disguise third-party cookies as first-party, preventing filtering based on that categorization alone. It seems it's getting harder to rely on browsers working how they were originally intended.
That's because people want to Do Cool Stuff™ in their browsers - ie, they don't want to merely "browse"
