A little tricky to set up.
Very nice indeed when I set it up correctly.

So great!

Really nice I can see the dang bar again, thanks! (I'll give five stars if you let us choose width and height.)

One star beacause this is useless and for the highly misleading introduction:

"Get the mouse scrollbar you've always wanted—specify width and color."

Yeah. You can can specify the width, NONE OR THIN. And that does not even work. Whooohou.

Works well enough. Good for completing custom themes, gets rid of the ugly grey scroll bar. Will not work on every website, but most.

Not useful. I've been trying for years to get rid of the useless Firefox scrollbar, which I never use, because it is too thin to try and click on it. I thought this add-on would allow me to finally do so. However, as clearly stated by the add-on when you try to change the scrollbar width, this is not allowed by Firefox. You can only change the scrollbar colors, but I don't know why anyone would want to do this

Does what it's supposed to do well. I love it

muy bueno
