When I access my Website (website A) with Safari (v 10.1.1) via a link from another website (website B), the access (in the real-time section) is seen as direct access.

With firefox, I can properly see the referrer (website B), why?

A couple of notes:

1. Before doing the test, I deleted all the cookies
2. The link in Website B to my website didn't contain the `noreferrer` attribute
