Last week, Firefox 4 launched with a host of new features and was quickly downloaded by nearly 40 million people and counting. Google's Chrome browser is only two years old, but is already packing a punch with its helpful shortcuts, plug-ins, and more. Safari and IE are classics, and they come preinstalled on Macs and PCs respectively.

I've been a Firefox supporter for years, but as Chrome grows in popularity, so does my use of it. What about you?
