In Alpha, but great! Rated 5 out of 5 stars

Despite being in it's Alpha phase, it works really well. Have only had one issue with a browser conflict with "AVG Privacy Fix". Available for Chrome too, which is well known for lots of tracking. It will surprise you how many trackers are there. I expect great things from the EFF and I'm certain this will become a very useful add-on as it grows.

This review is for a previous version of the add-on (0.1.2).
