I love this addon, but it suddenly stopped working when I updated to Firefox 65. Xubuntu 19.04

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!

タブの高さがでかすぎるんだよなぁ。

This extension is THE ONLY THING THAT MAKES FIREFOX USEABLE. Other browsers don't have it, and using them is like pulling teeth. However, it was no longer valid with the most recent update of FF and wasn't working. To fix it I just did a temp uninstall of FF and when I reinstalled it was back.
