It does not seem to monitor actual requests but only references. I block a lot of domains but they still appeared in this add-on.

  How are you blocking them? Sites blocked by RequestPolicy and Ghostery don't show up.

    In my router! I guess it returns a.status that the tool interprets successful connection.

      It probably counts when the request is made, without waiting for a connection to be successful.
