Firefox 1.0 is finally out and I strongly suggest you get yourself a copy. It's probably the best browser available for windows at the moment. I use it at work (although I probably shouldn't) to see how my sites are supposed to look; then I make the appropriate tweaks for Internet Explorers relatively poor standards support. Oh, and if you dabble in web design as I do, you should get the Web Developer extension. I use it a lot and it's a very handy tool indeed.
