I personally use firefox with pentadactyl, which by default removes the URL bar. It was a bit akward at the beginning but it's a major gain of space (especially in fullscreen mode) and there's nothing I could do with the URL bar that I can't do with keybindings.

For instance, if I want to edit the current page's url, I type "y o <cmd v>" to paste it in the status bar.

You might be interested to know that pressing "O" does the same thing as "y o <cmd v>" ;-)
