From bug 279099 comment 267: > See http://www.idnnews.com/?p=7109 > > Chrome displays the fake www.аmazon.com as http://www.xn--mazon-3ve.com/ on > hover, but Firefox still shows it as http://www.аmazon.com I get the impression that links where the domain is %-encoded work in Chrome but not in Firefox. Which is bug 309671, I guess. Spoofing on links that don't work yet, and only in the hover preview (which JS can spoof anyway), doesn't seem like the biggest security problem. But this should be fixed before the links are made to work. Probably related to bug 304905 and bug 320807.
