Mozilla Firefox 

Yes, the one that gets all the hype. Firefox don't forget to mention getting a certificate for helping to break a world record.

Firefox is a browser that I call a OSB (ObrowserS or OSbrowser) it sort of does everything that you don't really want like in a recent BETA they put a plugin that covers other plugins like flash & shockwave-why does a browser come with a plugin that well replaces other plugins & makes things look bad. But apart from that it's what I think is the best browser around. Also Mozilla think of names for stuff so they don't sound boring like the "awesome bar" instead of Internet Explorers lazy name: "URL bar." And with the ability of running on both Mac & Windows smoothly it's a winner.

Pro's:

pretty quick
awesome bar
looks great
has heaps of plugins
great UI
works on Win & Mac

Cons:

can't open more than 1 page at start up (unless you saved the tabs from the last session)
