I don't get whats so special about Firefox's awesome bar... all the browsers have it, the only difference is that Firefox is the only one that stores the additional meta information. When you type something into OP or IE, it has a drop-down menu that lists your history and favorites as well.
I use firefux over everything else because a lot of webpages screw up for me in IE. (Like websites with custom profiles, etc.) Also, I like my foxytunes, fireNES, foxclocks, and other stuff I use.
