Wonderful add-on that I've been using for years. By far one of my favorites!

I have just a small request for a next release:

- Could you add the ability to modify the scrollbar color in the CSS code? My eyes begin to become a bit old and a mid-grey on a light grey as currently becomes not enough even with the largest width, so an option to give any color to this scrollbar would be wonderful. I currently can't see this option within the snippets.

Possible?
:-)

Cheers!

很不错的一个插件，功能很强大，很人性化，很多细节可以自定义，这个非常好！

Great addon

Excelente extensión llevo apenes 2 días usándolo y me hace la vida más fácil.

Esto es por lo que uso Firefox, por sus grandiosas extensiones.

Pas mal, mais serait-il possible de pouvoir réduire la largeur des onglets comme le faisait les anciennes versions ??

An essential addon for the freaks of navigation tabs, like me. It is a tool that contributes greatly to productivity and organization when the amount of tabs verge of chaos. Thank you @piro_or for this great work!
