Rated 5 out of 5 stars
Excellent for keeping you more secure and increasing your privacy plus reducing the amount of adverts/annoyances. It's simple to use and, whilst it does take a little while to 'train' it initially to block or allow sites/domains, it's not difficult & well worth the effort. Sadly it's not yet compatible with FF57 but I can't wait until it is: I've tried the rest & this is, IMHO, the best. Thanks guys!This review is for a previous version of the add-on (1.0.beta13.2).
