Great upgrade! Rated 5 out of 5 stars

The previous version was great, but this is thrice as nice now. The addition of a choice of three quick profiles is a good idea well implemented.
This really does a good job of improving scrolling in Firefox, both for fine control and quick page scrolling. Can't live without it, once you use it.

This review is for a previous version of the add-on (2.0.1).
