Windows 7: [Firefox Auto Scroll] Cosmetical Issue! D:

Well, just as the Title implements, I gon some kind of cosmetical Issue with my Autoscroll in Firefox.

As some MIGHT know [ =P ], you can Autoscroll by pressing the middle Mouse Button in many, almost all Applications. Works just fine, but... in Firefox, there's some kind of a... Box, which my Autoscroll Symbol is displayed in.
Looks kinda odd O_O;



The only Application that somewhat cages the poor Autoscroll Symbol! D:

Is anyone out there to help me set my Symbol free again...?
It's just, the Symbol itself looks so pretty 'n shiny.
But the sharp black Frame around it disturbes my Karma on the Internet! D:

So, any Idea of what I could do, other than get a Life...? XD


Probably helpful Information:
It's a Laptop. Ya know, one of these practical things with Touch Pad and Stuff. :3
Plus, I use a Razer DIAMONDBACK 3G with Software, but that hasn't to do anything with the displayed Symbol, has it...?
