This makes it so the top Facebook bar is stationary (it stays in place even when scrolling). This way you can always see your notifications icon and have quick access to that toolbar even when you are scrolled down to the bottom where it would normally not be visible. Works with normal Facebook layout as well as my Facebook themes (may work on other Facebook themes, but I haven't tested)

2/19/10 - FB changes made the top bar contents within the top bar not be stationary; it is fixed now.
