I'm using the firefox browser under a proxy. Today I entered an url (the google project www.movikantirevo.com), it translated to the url www.movikantirevo.xn--com-6na. It never happened before, and after a little time it returned back to normal. Why?

This is an Internationalized Domain Name (IDN), which allows non-ASCII characters to be used in domain names via Punycode encoding. IDN fragments begin with an ASCII Compatible Encoding prefix xn--, which signifies "eXtensible Name".

The value you specified translates to comù, or comù in HTML encoding.

As to why this happened - I have no idea. The domain doesn't resolve for me. Perhaps it was a redirection glitch on their end.

this happened because the ù is near my enter key, although I couldn't find anything about it googling. Many thanks – Gabber Sep 21 '12 at 7:54
