Rated 5 out of 5 stars

Really useful with a well designed user interface. Blocks whole hoards of tracking scripts, cookies, etc. across the web, from the well-known names to the more obscure, with no apparent detrimental effect on my browsing experience. (The only tiny problem I have had is that /some/ eBay pages get blocked completely, but I only have to untick the eBay tracking "bug" from the blocked list, either temporarily or permanently, for them to work again.) Love it.

This review is for a previous version of the add-on (2.8.0.2).
