Web
I'm a Firefox user, have been for years. I love Microsoft products and most of their software is fantastic, but I have never been much fond of Internet Explorer. Maybe its IE's UI, or maybe its the fact that it doesn't have many great plug-ins. Either way, I much prefer to use Firefox as my browser of choice when developing web applications. There are tons of great add-ons available to Firefox users to make their web developing lives easier. Here are my favorite 5: Firebug - This one's got it all: JavaScript debugger, DOM inspector, traffic analyzer, CSS inspector, and much more....
