It doesn't seem to work with Facebook.

Sorry to hear that! Unfortunately, with the new Facebook design, they've made it impossible for the add-on to customize the scrollbars. Instead of using the standard scrollbars, they have built their own scrollbar system from the ground up so that they can have full control over the appearance of the way the scrollbars look and behave.
