At the top of the browser, you can right click, then uncheck the boxes for the navigation, bookmark and menu bars. This makes the window larger. However, since I unchecked all three, I can no longer right click to get them back. When I move my mouse to the top of the browser and right click, all it asks me is if I want to reload the current tab or open a new one. I want to be able to check those options again to view my toolbars.
