Needs update maybe... Rated 3 out of 5 stars

Very nice to customize toolbars and font, but the scrollbar change doesn't work. It stays as the original whitish bricks. (Using XP SP3 & FF 3.0.18.)

This review is for a previous version of the add-on (1.8.33). 

Version 2.0.14 is just uploaded,

Version 2.0.14 is just uploaded, supporting FF 4.0 upto 2.0.14!
