What Browser Do You Use?

Matthew Yglesias over at Slate posted the above diagram showing the rise of Google's Chrome and the fall of Microsoft's Internet Explorer as popular browsers used to access the World Wide Web.

I use Chrome as my primary browser but at work "for da gubmint" most of the applications are written to be optimally run using Internet Explorer.

According to this blog;s stats, roughly 37% of you use Chrome, then 22% Firefox, 19% Internet Explorer and 9% Safari.

What browser do you prefer to use?
