Sidebars! If you take a day to get used to the using a sidebar for browser tabs, you'll never go back. I prefer Tree-Style Tabs on Firefox, but it's far from the only option. Then again... even with that, I guess I agree with the OP. Even after turning on the sidebar, there's more horizontal space than I need. And I love screen real estate. I long ago got used to black bars, and don't watch that much video on my laptop anyway. Usually when I do, I'm connected to an external monitor.
