Although it is not perfect yet, it is already far better than its former rival "Adblock Plus" - especially after the last biggest update (and mistake!) of "Adblock Plus" v. 3.0+ (v. 3.4.3 precisely in my case when I have finally lost my patience and decided to abandon "Adblock Plus" for good for not supporting its previous functionalities that I got used to for many years until now). See my comment there for more details if you really care. The browser extension/add-on "uBlock Origin" for Firefox v. 64.0.2 is so good, in fact, that I can hardly find anything to complain about - it really does its job!
