That's what I love about it, I can shape this thing to fit the way I like to think, so surfing flows much easier on the brain. I'm taking in more content inless time than I was ever able to with IE.
The way I have FireFox set up is a long way from default. I have the tabs down the left side, bookmarks to the right. I got that menu-shrinking extension, and I find that I can comfortably fit all of the toolbar items onto the menu bar(navigation buttons, history, bookmarks, google, address).
I have a fairly high resolution screen, so the end result is a very clean top and easy access to everything I need, with nothing to visually distract me from the viewing pane.
Exactly, FF can be configured nearly any way the user wishes. I stick with the stock browser appearance for maximum visible screen, and then use extensions like Tabbrowser Extensions, GMail Notifier, and Weatherfox to turn FF into my second desktop.
Can't wait for 1.0 final.
