How Mozilla is moving forward to make ads and privacy coexist

> Our focus is on technologies and methods like differential privacy, encryption, aggregation, and multiparty computation, which allow advertisers and publishers to derive insights about advertising performance without sharing user data with each other.

Well, that's the controversial part, isn't it? I agree that ads and privacy can coexist, but I disagree about the method by which that can be done. It can be done by eliminating the data collection and doing contextual advertising, not by trying to find some technological method to take the edges off the spying and turning the browser into an active collaborator against the user.
