A simple Add-On that makes scrolling nicer, smoother. Rated 5 out of 5 stars

I'd previously used another scroll tweak Add-On. It was good. No complaints, but, YASS is MUCH easier to set up, more ways to configure. I love the little 'bump' and slight return you get when you hit the top or bottom of a page. As Add-Ons go it's not an 'earth-shattering, 'biggy,' rather, YASS is just a real nice Add-On that enhances your movements on a website.

This review is for a previous version of the add-on (3.0.14).
