Rated 4 out of 5 stars

Really not a bad addon ... I made sure to do a "skin" online Adobe PDF Reader ... makes her well ^ ^
The worry is that the horizontal bars do not work at all when the width is less than 11 ... and even 11 precisely area "click" only 1 pixel ... should adjust its is a big concern . I had the same problem with an option to keep the bar above the content in HTML pages.
So I put 4 stars for now ;)

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


Not every available option works everywhere with all plugins and on all OS. Ecpecially MacOSX likes to break things, but also Adobe plugins.

I believe Adobe controls scrollbar width inside their pdf plugin at least partly.
