I uninstalled badger back when Firefox released cookie isolation. No need to learn about tracking cookies when they’re either blocked in the first place, or isolated meaning no cross tracking.
Privacy Badger go beyond blocking cross-site cookies:
Privacy Badger comes with other advantages like cookie blocking, click-to-activate placeholders for potentially useful tracker widgets (video players, comments widgets, etc.), and outgoing link click tracking removal on Facebook and Google.
Privacy Badger can detect canvas-based fingerprinting, and will block third party domains that use it. Detection of other forms of fingerprinting and protections against first-party fingerprinting are ongoing projects. Of course, once a domain is blocked by Privacy Badger, it will no longer be able to fingerprint you.
