Can't login with FB's login on some sites on Safari
Safari 11.0.3 macOS 10.12.6
Have the next problem - on some sites I can't log in with Facebook as it keeps "loading" all the time (deezer.com/freelitics.com). Tried other browsers(Opera and Chrome) - all ok. But I need it here, on Safari.
Disabled AdBlock and Anti-virus didn't make any difference.
