If you haven’t tried Firefox yet, you owe it to yourself to take a few minutes and download it. It’s the world’s most popular browser, and offers improved security and lots of handy features. Visit their site at:

We develop all of our sites initially using Firefox – partly because it’s one of the most standards-compliant browsers (i.e. it works they way a browser is supposed to), and also because there are lots of great extensions that help developers. Once they’re working and approved, we make sure they work (almost identically) with all the browsers in our compatibility list – typically: IE6, IE7, IE8, Safari, and Chrome. (The compatibility list is negotiable for any given site.)
