One problem in my laptop is small screen size (1280 x 800) especially in vertical axis. It make me annoyed although most of website and mouse are support to scroll in vertical but I tried to reduce a size of unnecessary component in browser such as menu bar, toolbar and bookmark toolbar. Finally, my bookmark was reduced to a single button in an address bar with some necessary buttons includes: back/forward, reload and stop. The menu bar was reduced to a single button by browser extension. I selected only a need and frequently in use command into my reduced menu bar.
Chrome 6.x from Google going to the same way, it was reduced 2 menus into a single one and most of the component is similar to my reduced menu bar, see figure below. Major browsers that concern in usability may convergent in to the same way.
