Confirmed. 
It is also true in Thunderbird!

We're also talking about it not getting "thicker" when hovering, right?  Although, with 10.9.2, I see that problem on 31 (trunk), but not on 30 (aurora)

Further, for me, I actually can't use the scrollbar to drag in this case.  I imagine a dupe, but I opened bug 993517 for it.

I believe that this bug, as written, is expected behavior. When scrollbars are always displayed (by enabling "Always show scrollbars" in the System Preferences, the size and color of the scrollbars shouldn't change when hovered. :lizzard, am I missing something? How does Safari behave?

However, bug 993517 is a valid regression.

Fair enough - I missed the "always show scrollbars", so all of my comments are based on the default, where they scrollbars only show up once you start scrolling.  The behaviour there changed here: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=e84a391b604b&tochange=c148f0b0c8b4

I have 'Show scroll bars' set to always, and scrollbars become darker when I hover over them in all applications except us.

Comment 7

[Stephen A Pohl [:spohl]]

Ah, I just realized that the thumb is getting darker. So this is a valid bug, but not a regression and unrelated to bug 993517.

Comment 8

[Markus Stange [:mstange]]

Comment 7 is right. We never had a hover effect on non-overlay scrollbars on Mac. We should add it.

Comment 9

[Markus Stange [:mstange]]

Bug 1016569 implements the hover effect. (I filed a separate bug for it because I don't want a bug about hover effects to be included in the dependency tree for async panning.)

Fixed by bug 1016569.
