Tabs and Url bar on same toolbar in web browser

Question

Does anyone know of a web browser that puts the tabs, url bar, back/forward buttons, etc... on the same toolbar by default? I know this is possible in Firefox but it never looks very good. Something like this:

Or maybe, do you know of a theme/extension for Firefox or Google Chrome that puts them all on the same bar and still keeps its good looks?

Answer 1

It's a Mozilla Labs Project, so there is a chance if it is successful, it will land up as a default feature of Firefox.

Answer 2

Internet Explorer, as it happens.
