Rated 5 out of 5 stars
Better than the Chrome version, which I've been using problem free for over a year. Blocks Facebook tracking widgets, but shows you what's blocked and lets you unblock if you want to Like or share.This review is for a previous version of the add-on (2.0.2).
I think this is our best (Chrome, Firefox, or Safari) extension so far, too. Thanks for using and reviewing.
