You might want to check with Comcast SmartZone support about that issue, I suspect they did an update earlier this week. As of yesterday a Firefox 2.0.0.20 user who posted here couldn't even get the the comcast.net homepage to load, and I can't either with Namoroka/3.6.18pre - ''(the "tester version" of Firefox 3.6.x updates)'' - we're getting re-directed to the "unsupported browser" web page at Comcast. The strangest thing is that Comcast doesn't re-direct Aurora 5.0 as being "unsuported", they know that is Firefox-next. And today when I logged in with Firefox 4.0.1 all the emails that I read yesterday with that same browser were '''bold''' as being un-read. Comcast changed "something" on either Tuesday or Wednesday.
