μBlock Origin is an efficient and general-purpose web filter plugin for browsers. It's primarily used for ad blocking of course. Runs in Firefox, Chrome, Opera Blink, Safari, Fennec, and other Chromium-based browsers. It automatically uses EasyList, EasyPrivacy and Malware Domain filter lists, but also supports hpHosts, MVPS HOSTS, Spam404 and many other curated block lists. μBlock is speedier and more memory conservative than other ad blockers, and is completely open source, does not undermine filtering like ADPs sponsored ads.
