I don't like FF3's "Awesome Bar" so I disabled it. I tried using it for a while, but noticed I mostly type in things like "n", "r", or "t" to get to news.ycombinator.com, reddit.com, or my own domain, respectively, and with the "Awesome Bar" this is removed and it actually takes me LONGER to browse, as I generally type in a letter or two of the URL and go to it directly.
