Rated 5 out of 5 stars
I do my best to maintain some level of privacy with minimal impact on convenience, and this add-on does a great job of showing how effective my methods are. I'm glad to say that almost none of the connections are through cookies.
I'm not sure when the Tracking Protection feature was added, but I understand this to be at least related to "Polaris", which we might see in Firefox 38.
Mostly, this serves to show just how little control we have over privacy online. Even with all my attempts to preserve some degree of privacy, tracking sites outnumber visited by at least 2:1.
