This is useful in that it limits the set of people who have access to your browsing history. But first party tracking will still be a thing (i.e. if you are visiting a website, the owners of that website will know you are visiting it). Actually there is a paper that says that if you only use the New York Times links that people click on from Twitter, it still makes you uniquely identifiable in many cases, so a company like the NYT could (theoretically) track people without using any third party tracking at all. http://cosn.acm.org/2014/files/cosn012s-chaintreauAemb.pdf http://cosn.acm.org/2014/files/cosn012s-chaintreauAemb.pdf
