Yes, it also happens with FF (as I reported above). I do not use the HOSTS file at all. Other than 127.0.0.1, there is no entry. If I do View Source, this is what is there:-
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD>
<META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD>
<BODY></BODY></HTML>
