Stage 1: Definition

1. Feature overview

We are going to enable smooth scrolling by default on mozilla-central and see how if there are any issues with mouse/touchpad drivers. If any issues are found with mouse/touchpad drivers, please mark those bugs as blocking this bug.

See bug 710372 for details.

2. Users & use cases

Smooth scrolling is the animated sliding effect when you roll the scrollwheel. Without it, the page jumps one or several lines at a time when scrolled. It's a subtle effect, but it makes it easier to follow content as it moves and is a more enjoyable effect. It also compares more closely to touch-based scrolling and so increases consistency across PCs and touch-based devices.
