Smooth scrolling Rated 5 out of 5 stars
I can't imagine to browse without this Add-on. There are many options to configure the "smooth scrolling" behaviour to your personal taste. Great! :-)This review is for a previous version of the add-on (3.0.19).
Rated 3 out of 5 stars
As others said the 3er Version performs very bad. I got very annoying stuttering and jerking with mousewheel - no smooth scrolling.
I had to go back to version 2.0.25 which works great.
