Very excellent. No false reports either - I run sites with no tracking and this add-on confirmed it. Options are a bit confusing - you have to go through the Add-On Menu and adjust them there - you get a list of what has been blocked and you can change which ones you want unblocked. It also will block on a site-by-site basis. No slowdown issues noted.This review is for a previous version of the add-on (184.108.40.206-signed).
