Gerrit trying to set 3rd party cookies

After watching Sarah Bird's great talk about the terrifying web[1], I found that for some reason 3rd party cookies were enabled in my browser. After disabling them, I found that gerrit is using 3rd party cookies from gravatar.com. (see attached screenshot). Why do we allow 3rd parties like gravatar to set cookies? Can we use gravatar without setting cookies? [image: Screenshot from 2018-07-01 15-31-37.png] [1] https://il.pycon.org/2018/schedule/presentation/18/ Nir
