👍 Useful indeed and well made.Thanks!

*sigh of relief*

Finally I can stop straining my eyes trying to find that light-grey-on-lighter-grey-next-to-white right at the edge of my screen.

Ce module est excellent ! Quelques fois, les barres de défilement sont trop minces et de couleur grise / grise ! Presque invisible ! Avec ce module, je choisis la taille, la couleur. Que demander de plus ? Merci !

This module is excellent! Sometimes the scrollbars are too thin and grey/grey in colour! Almost invisible! With this module, I choose the size, the colour. What more can I ask for ? Thank you !

Fun! Simple! Yay!

Wow, also works on Firefox Nightly Android.

Заявленная функция работает и интуитивно легчайше понятно, как включается.

Easy to use and works well.

Wow I love it

Настройки:
Scrollbar width - Platform Default
Scrollbar thumb color - #1d89f2af
Scrollbar track color - #a69e3128

Жаль что нельзя сделать полосу чуточку шире как в Google Chrome.

This is a primary extension (choose Use Custom Colors) which I think should be a default part of FF.

And changing widget.non-native-theme.scrollbar.style to 4 (from 0) in about:config (and hit the Save checkmark) makes it wider.

And I read with disappointment about the response to the developer by FF to enable wider widths:

Rather, as Custom Scrollbars beatifically examples, customization enhances browsers. Thank God.

(Note that Custom Scrollbars will not work in Firefox system pages as this).
