chrome keeps both domain and subdomain black, which makes this kind of phishing easy. Firefox have a better approach of keeping black only the main part, and graying out everything else. Yet better solution would be to highlight domain with green color instead of https://, and to scroll urls with very long subdomain to make domain viible.

I rather liked how this[1] firefox addon added a bubble around domain, but kept url as selectable text.
