On most web pages, when I use the scroll wheel on my mouse, the screen keeps moving for a second or more after I have stopped moving the scroll wheel. I would like the screen to move only for the precise time I am moving the scroll wheel, no more, no less. I have disabled Smooth Scrolling, to no effect.

This is most irritating when I go to control-click a link to open it in another tab. Since the scroll action has not actually stopped, Firefox interprets this as control-scroll, which adjusts zoom settings.
