How does the Brave browser protect against sites that a person has already logged into?


I understand that the Brave browser does not allow for 3rd party cookies to be set so that a user will not be tracked by a 3rd part site.

However if I were to log into a site like Facebook and navigate to a site that is using a Facebook pixel, my understanding is that the following will occur:

  1. After logging into Facebook, a Facebook cookie is set in the browser.
  2. I navigate to a site ( that is using a Facebook pixel.
  3. makes a HTTP request to retrieve the pixel. The cookie set by Facebook in step 1. is also sent in this request, perhaps along with some other information as well (via a query parameter?).
  4. Facebook will now have knowledge of the fact that I have visited

If my understanding of the above steps are correct, does Brave have a method to protect against this?

Thank you!
