The local learning feature of the privacy badger extension learns to block trackers on its own, so it can block trackers that are outside of Firefox's tracker list. The Privacy Badger keeps track of the tracker's domain and the domain of the website that saw the tracker. If Privacy Badger sees the same tracker on three different websites, it will start blocking that tracker. I'm not saying that you guys want to have this extension built-in, I'm hoping that Firefox will have something like a privacy badger, hasn't Mozilla been focusing on AI lately, maybe with the help of AI to identify trackers and block trackers
