Questions to the people from Mozilla who're here. How or why is this different from efforts like Privacy Badger (from EFF)[1] when you look at what gets blocked, the methodology used to update the blacklist, etc.? Was there any collaboration with other prominent players working in this area (I only see that you're using disconnect's list)? Please note that I'm not talking about implementation details like the creating and maintaining a content block list for Safari vs. a browser extension on the desktop.
