Looks like both Mozilla Firefox and Internet Explorer have gotten some major updates in the last few days. Download here:

Firefox:
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/2.0/

Internet Explorer:
http://www.microsoft.com/ie

My take? As a web developer, the new changes in IE, especially in regards to handling Javascript...suck! The tabs are good, but LONG overdue. I'll be sticking with Firefox, but since I AM a web developer, I have to test on both...

The Firefox updates are mostly good, but I guess I was the only person in the world that liked a centralized button for closing tabs. That has changed so that each tab now has it's "own" close button. I liked it better the way that it was, but maybe I'll get used to it...or maybe it'll be an option that you can turn on/off later. That'd be best!
