Element inspector Anyone familiar with uMatrix (on which uBlock Origin is built) should feel right at home here. It’s mostly useful for fixing pages that uBlock Origin has otherwise broken. Only available to Advanced users (enable in the Settings tab of the Dashboard), dynamic filtering allows you to tinker on-the-fly with which scripts and domains you allow a web page to load. We haven’t tested this ourselves, but what is certain is that its footprint is likely to be negligible on any modern machine. The more filters you use will cause uBlock Origin's memory consumption to increase, although the developers claim that this still remains low compared with most popular adblockers out there. An interesting comparison with AdBlock Plus is available here. UBlock Origin is an efficient adblocker with a small memory footprint and low CPU overhead. Google recently rejected uBlock Origin from the Chrome Web Store, but following an angry backlash from fans and developers alike, who accused Google of abusing its dominant market position to shut out rival developers, Google caved in and reinstated uBlock Origin in the Chrome Web Store. UBlock Origin works in the Android versions of Firefox and Chrome, although Apple’s restrictive developer guidelines prevent the iOS/iPadOS versions of these browsers from supporting any browser add-ons (including uBO). It was available for Safari but has sadly been borked in Safari 13 Catalina by Apple’s dumping support for legacy safariextz-style extensions. It is also possible to import custom lists from hosts files and to whitelist domains as you see best.

It uses community-based blocklists to filter out unwanted traffic, and users are free to add new blocklists as they please. UBlock Origin shares the same codebase as uMatrix, which performs a similar job, but which is aimed at more advanced users. We cannot emphasize enough that uBlock Origin should not be confused with uBlock, the latter of which is now owned by Adblock Plus and participates in its "Acceptable Ads" scheme. Developer Raymond Hill “self-forked” uBlock Origin after transferring the original uBlock project to a different developer in 2015, after which time the two projects have been completely separate. UBlock Origin is a fork of uBlock, but both have the same original founder. UBlock Origin is a browser add-on for Firefox, Chrome (including Chromium and Opera), and Edge.

Of course, the more filters enabled, the higher the memory footprint. More lists are available for you to select if you wish: Out of the box, these lists of filters are loaded and enforced: It applies to the current web site only, it is not a global power button.įlexible, it's more than an "ad blocker": it can also read and create filters from hosts files.
