[Rubber Duck]

Yes Bull Shit to spell it out in full. Mozilla know that the only extension that is going to result in significant Phishing attacks in the US, whic appears to be the only place that matters, is dot com. The others are just Window dressing. Because they haven't done the development work that Microsoft has to introduce a plausible system this is a convenient fudge. It is, however, evil because it promotes the myth that phishing is essentially caused by IDN. FHs.
