Add LIVEditor [http://liveditor.com], although it's single-purpose is for css, html and js only. It uses Webkit too, but for live preview of css and html changes only, like the real-time effects you can see with Firebug or Dev Tools.

The videos on your site don't load for me. I've turned off ad blocks...

Thanks. The homepage was using the <video> html5 tag, looks like some browsers don't support them well, I finally decided and have changed to youtube video instead...
