fast and clean have used it for a few days now without any chrashes, which is batter than I can say for OSX versions (and non beta at that) of netscape and explorer. One problem though is that if you are in a multiframe page with a text entry field (say a company search page or a web chat site) when one frame refreshes you loose your text insertion point in another frame :( Fix that and I'll give it a 5star rating
