Personally, I also find it important that Cliqz is based on Firefox, other than almost all the other new browser projects out there which are based on Chromium. There is nothing wrong with Chromium, but I believe some choice / friendly competition in rendering and JavaScript engines is important for the overall well-being of the web.
That sounds an awful lot like the Electronic Frontier Foundation's Privacy Badger.
Did they change that?
