Running a small screen like my netbook, I can get the most amount of screen space using Firefox with various add-on's and themes. way more than IE or Google Chrome
here is an example of the screespace I get on my 10" netbook and the add-ons I am using to get the screen real estate
Basically 2 small rows at the top using Micro Fox theme and the rest is open for browsing.
I use Farstone capture to get my screenshots, its pretty handy little app
