Firefox scrollbars missing thumb -- workaround that's pretty enough to use even without the bug

This is primarily intended to be a helpful note to anyone dealing with=20
the problem where recent firefox, possibly only when built against gtk3,=20
loses its scrollbar "thumbs", a problem I was seeing here, with the=20
mozilla-built binary[1], but others may find it worthwhile, and=20
beautiful, as well.

A google suggests the problem is gtk-3.20-related, as one poster found=20
that downgrading to gtk-3.18.x returned his scrollbars.  However, I=20
wasn't particularly thrilled at the idea of downgrading so I continued=20
googling.

Fortunately there's a rather nice workaround in the form of the=20
"NewScrollbars (aka NoiaScrollbars)" extension.  Yes, that's the name,=20
including the aka in parentheses.

They're customizable color-gradient scrollbars that as one of the reviews=
=20
says, are "Way better looking than the default."  "Just classes up the=20
appearance of the page.  Great useful add on."

Even *more* "useful" and "great" when they avoid a bug in the default,=20
but now I'm glad I had the bug as I'd have been unlikely ever to find=20
them, otherwise, and they're both rather pretty and customizable enough=20
to work with my "reverse" color scheme with light on dark! =3D:^)

[1] Mozilla-built binary: Since IMO gentoo seems to be late with updates,=
=20
potentially fatally late, for what's likely the most exposed app on the=20
system, so now I get the builds direct from mozilla.  I do understand=20
that the gentoo maintainers have to make sure it actually builds on the=20
wide range of what gentoo users have installed and that's not always=20
exactly simple, but even when the update's available even just a week=20
after the upstream release, when that could well be five days vulnerable=20
to an active exploit, it counts!  So I'm not exactly happy with the idea,=
=20
but I'm grabbing the binary direct from mozilla now, and letting firefox=20
itself handle the updates.  At least that way I get them the day of=20
release or so, not generally days after release when I may be already=20
exploited if I'm waiting on gentoo.
