Hello, just thought I'd randomly post in and say that yes, Fire Fox (the browser formerly known as Fire Bird which was the browser formerly known as Phoenix ;) ) is gooood.
There are plenty of good extensions (
http://texturizer.net/firefox/extensions/) to chose from to, which basically let it do anything any other browser can do for free and usually very small downloads.
"IE View" is useful for the occasional page that doesn't work (adds an "Open in IE" to the right click context menu)
And holy crap, cool to see lotsa stuff going on around here :)
