Rated 4 out of 5 stars

Excellent add-on. Easy to use and informative!

Could be improved by auto-updating block lists (I still seem to have to go into Settings after an update to add new ones....maybe I am missing something).

Also, some continuing attention needs to be paid to impact on page loading times but is tolerable compared to clean Firefox load times.

This review is for a previous version of the add-on (2.9.4.1-signed).
