The title is the string I was looking for when I needed do to this.
Since I use Google reader on my Netbook, I like to use fullscreen view to maximize pixels.
I just hate how slow it takes to switch between modes because of the silly ainmation of the toolbar/awesomebar which forces the browser to redraw the content after each pixel.
Well, here's how to disable that. As expected, go to about:config and search for the string:
browser.fullscreen.animateUp
And set it to 0.
