As a web developer, my main browser is Firefox. I have to use the excellent Firefox extension Firebug for my web development.

To test the webpages in multiple versions of IE, I use IETester. my-debugbar. com/wiki/IETester/HomePage.

I also use Safari and Chrome to test how the webpages render in the WebKit browser engine.

There are so many browsers out there that it's impossible to test how the webpages render in each one. Therefore, I use browsershots. org/ and then I see a picture of how my webpages render across a bunch of different browsers and platforms.
