I just saw this on Yahoo! News - FireFox has been downloaded 100 Million Times, even before their one-year anniversary. Pretty impressive.

Gotta say, I love my FireFox. Compared to Internet Explorer, well, there is no comparison. If you do decide to give it a try (or you already do), make sure to find a good theme - I have the 'Brushed' theme, and, I must tell you, I find it mucho wonderful-o.
