I recently discovered that Ghostery was purchased by Cliqz [0], which is a company partially owned by Mozilla. They offer a free privacy-oriented browser "Cliqz" which is described on Wikipedia as:
"Cliqz plans to eventually monetize the software through a program known as Cliqz Offers, which will deliver sponsored offers to users based on their interests and browsing history. However, these recommendations will be processed locally based on a remote repository of offers, with no personally identifiable data sent to remote servers." [1]
I haven't looked further into it, but it makes me feel like I should contribute to a browser project...
