Rated 5 out of 5 stars
I love this extension it works like a dream. :-)This review is for a previous version of the add-on (0.45.6.20100202.1.1-signed.1-signed).
SmoothWheel is fully compatible with latest Firefox (and nightlies etc). I'm using it on many computers myself, and if an update was required, I would have updated it ASAP.
