The idea is that for untrusted top-level domains, they will at least convert to the wire form and the end user might get that something is up when they see http://www.xn--pypal-4ve.com/ in their address bar after they type in paypal.com with a cyrillic 'a'. All top-level domains are untrusted (including .com), unless Firefox has whitelisted them. Its whitelist is quite small.

Good question, and I don't know the answer. In Firefox you can inspect what your whitelist is set to by going to the URL "about:config" and scrolling down to the settings with the prefix of "network.IDN.whitelist"... there should be an entry for each top-level domain that is whitelisted. It could be there is a "network.IDN.whitelist.com" entry in there inserted at some point.
