Hmm, I don't think that was the point of the movie. It was more about social media, and no adblocker in the world will save you from Facebook or Google or YouTube tracking your usage and recommending ex boyfriends or "rabbit hole" videos to you.
In fact, with the exception of one scene, I don't think a computer was even shown – all the interactions were apps on phones.
(They did mention, at the end, extensions for blocking recommendations.)
