Block lists in Firefox

You can change the block list used to block third-party trackers. By default, Private Browsing with Tracking Protection uses the Disconnect.me basic protection list. You can change this to use the Disconnect.me strict protection list instead.

• The basic protection list blocks commonly known analytics trackers, social sharing trackers and advertising trackers. However, the basic protection list allows some known content trackers to reduce website breakage.

• The strict protection list blocks all known trackers, including analytics trackers, social sharing trackers and advertising trackers as well as content trackers. The strict list will break some videos, photo slideshows and some social networks.
