I use Netscape  

No longer developed, but supposedly SeaMonkey is its natural descendant / replacement.

EDIT:

I used to use IE, because I thought "Hey, this is a browser. And it's preinstalled. Why should I use some other browser?". Then I read about security in browsers and switched to Firefox. And it also had Adblock that could finally rid me of those pesky Flash ads, that run around the screen playing cheeky sounds or weird music. And popups. They also died. Recently I've switched mostly to Opera because FF has been getting so heavy.

Try Google Chrome (now at version 5 stable!) if you want speed.

Do I really need to point out that anyone who looks for SCP Project and think that means FS2_Open is an idiot because I am not a member of the Source Code Project Project.

I think the other SCP is actually the SCP Foundation.
