The indie browser.

"The wait is over. Get Firefox 1.0, the faster, better web browser. Now available in 14 languages, for Windows, MacOS X and Linux.

'I suggest dumping Microsoft's Internet Explorer' — Walt Mossberg, Wall Street Journal."

This is the future (and present, for a lot of the people I know) of web-browsing.
Highly customizable, lightweight, good-looking, compatable with all the standards (yes, it opens practically all pages. The ones it doesn't, well, you just open with that old piece of junk that you can't really uninstall)
The tabbed browsing is sexy as hell, built-in pop-up blocking, amazing security.

I haven't used IE in ages. I'm glad the browser wars is back and turned into guerilla.
