Before switching to Firefox, using Chrome I was able to use the four arrow keys on my keyboard to scroll. When I wanted to have continuous scrolling, i just held down the ^ or v key. But on Firefox, I cannot achieve continuous down-scrolling (up-scrolling works). The screen scrolls down a few lines, then stops. I then must press the key again to advance the scrolldown another few lines.

I can't seem to alter this behavior no matter what settings I change in General Settings (smooth, auto scrolling). Is it possible to get continuous smooth scrolling in Firefox? If so, please advise how!
