I have yet to figure out if/how to change the scroll bar in firefox. I have everything perfect on my site, it looks fantastic in IE, but in firefox its the bleh standard grey/white. Is there anything in particular I need to do to make it work?

There is only one way to change the scrollbar colours in Firefox (http://developer.mozilla.org/en/docs/Creating_a_Skin_for_Firefox), and it has nothing to do with CSS, HTML, or your website. You cannot force UI changes upon Firefox users, thank god.

An alternative would be to use Flash. Or you could use Javascript to control the behaviour of elements that you could use to make your own custom scrollbar, like those shown here (http://www.java2s.com/Code/JavaScript/GUI-Components/ScrollBar.htm).
