Since we were just talking about HTML 5 support in the SilverLight thread I though I would post this. FireFox 3.5 RC supports HTML 5. http://www.slate.com/id/2221756/ Since FireFox has a major market share, this well mean great things for HTML 5 support and standards. Be sure to download it (http://www.mozilla.com/en-US/firefox/3.5/releasenotes/), and check out the demo (http://people.mozilla.com/~prouget/demos/). Some really cool stuff. I really like the Video + CSS stuff.
