Remember the article [ProPublica's _"Meet the Online Tracking Device That is Virtually Impossible to Block"_](http://www.propublica.org/article/meet-the-online-tracking-device-that-is-virtually-impossible-to-block)?
The title is obviously an exaggeration (the tracking _can_ be blocked), but the particular `addthis.com` javascript code which attempts to fingerprint your browser executes from within a 3rd-party `iframe`. Contrary to what Adblock Plus has been claiming on its blog and the media, using _EasyPrivacy_ does **not** prevent AddThis from fingerprinting your browser. This is something I verified and re-verified back then, and unless appropriate filters have been added since last time I checked, it still is the case.

AddThis and countless other 3rd-party which purpose is to data-mine you will be foiled by blocking 3rd-party `<iframe>` tags (even more so if blocking 3rd-party `<script>` tags).
