I really like this theme, however, I feel that it could be made better by adding an ever so slight transparent background to the search & address bars, or to slightly change the color of the text in the address & search bars. That would keep the simple, yet sharpe, look, while still helping to guide the gaze of the browsers user to places of importance. The address bar is also a point of reference by everyone who uses a browser, which is why all browsers implement one.
