For those who haven’t read the article, the suggested solution is for advertisers to obtain similar user IDs by using their own user list; it has nothing to do with gathering user data from the browser.

It is utilized in conjunction with other differential privacy technologies that gather user information and classify users.

In fairness, Mozilla needs a means of making money if anyone hopes Firefox or Librewolf to exist in the long run.

In OP’s screenshot, you are only going to agree to Mozilla’s privacy policy and FakeSpot’s TOS. So the FakeSpot’s privacy policy is not involved.
