Does anyone know if there is an extension, Stylish script, or Greasemonkey script to remove the gradient from Firefox 3 in Vista to make it look more like past versions?

I like the default theme, I just want to get rid of the gradient.

Well that does get of the gradient, but I don't want to change the theme.

No, I'm sorry, I should have been more clear.

While this is a picture of a beta build what I am trying to point out still exists:

The XP version, the "background" behind the toolbars is flat, while the Vista version, the "background" behind the toolbars has a gradient fill. The only major difference, is in the final build there are no horizontal separators between toolbars.

How do you (if currently possible) remove the gradient from Vista?

*Note* Having a little trouble inserting an image.

I will tomorrow, I don't have the Vista PC with me anymore.
