FireFox 2 vs. Internet Exporer 7

"Firefox is a global, open-source project, so development has been very swift when compared to Microsoft's closed-source development of Internet Explorer. We've had to wait a very long time between IE6 and IE7, so most users are installing IE7 with high expectations. The good news is that both browsers have seen some significant enhancements in three key areas: user experience, security and web standards. The bad news is that one browser still has better features and standards support than the other."
