Ask HN: What browsers do you use everyday? I use 2 simultaneously

I just read an article on HN about how Chrome made an 8.5% gain last month. And had to wonder why. I was wondering if anyone else works like I do. While at work, all day long, I use 2 browsers all day long: minefield (firefox beta 8, latest trunk) and Chromium 9. Sometimes I am forced to use IE 8 for corporate stuff, but I really don't like that. I am stuck on windows XP because I work for a corp. But at home, I use Firefox and chrome on my Ubuntu.

When I do HTML coding I test in every browser I can, using variants of the big 3 engines, gecko, Trident, and Webkit.

So what does everyone else use?
