Firefox scrollbar problem

[Philip Heron]

Hi all,

I've noticed since F22 I can't grab the Firefox scrollbar with the mouse 
pointer when it's on the very right of the bar. I have to move it in a 
pixel or two in before it works. It's like there's a thin inactive 
border around it.

Someone else noticed it too:

Anyone know a workaround? No other programs on F22 seem to have this 
problem, even Thunderbird.
