I tried out optimoz after a /. story on it, and I have to say that it needs work.. sometimes it will pick up a gesture when you are doing a quick drag of the scroll bar to the right of the html area, and I find that highly grating. *scroll down* ^new window pops up^..

I don't use Moz at work mainly because I don't like its bloat. I use either phoenix or winembed if I just need a render and no fancy features. It's a bit heavy at 12 megs to start, but winembed is a really nice option.
