Scrolling with the mouse is extremely slow, every scrollwheel "tick" zooms for maybe 1 pixel..

I've tried it on chrome also, scrolling works fine there.

@Azeirah: This does not seem to be the case for me, with Firefox 41.0 on Mac. What's your environment?

Tried on two different computers. Ubuntu 14.04 Firefox Dev edition 42.02a
And on a Windows 8.1 box with a regular Firefox installation.

Are you using the mac trackpad or a mouse? My guess is it has to do with the deltaY property of the mousewheel event,

I tuned this to work with the mac trackpad. There might need to be some code to normalize this value across devices.
