Firefox uses Disconnect's tracker list, but that's not enough, and I recommend using some ad filters' privacy protection lists to improve your privacy. https://raw.githubusercontent.com/AdguardTeam/FiltersRegistry/master/filters/filter_17_TrackParam/fi... and https://raw.githubusercontent.com/AdguardTeam/FiltersRegistry/master/filters/filter_3_Spyware/filter... These two links are very popular privacy protection lists, and we hope to use them in Firefox
