My Asus Eee PC 701 is a brilliant low-cost ultraportable notebook, but it has a really small screen (seven inches diagonally). I needed to find out how to make the best use of the available area when I was using the Firefox Web browser. I used F11 to toggle the browser’s built-in full screen mode, in which a modified navigation toolbar and optional tab bar are all that is displayed above a Web page, but I yearned for something even better. I found two add-ons that could meet my needs.
