However, Hill immediately self-forked it and continued the effort there. The uBlock project official repository was transferred to Chris Aljoudi by original developer Raymond Hill in April 2015, due to frustration of dealing with requests. First released in June 2014 as a Chrome and Opera extension, by winter 2015, the extension had expanded to other browsers. uBlock was developed by Raymond Hill to use community-maintained block lists, while adding features and raising the code quality to release standards. Development started by forking from the codebase of HTTP Switchboard along with another blocking extension called uMatrix, designed for advanced users. UBlock was initially named 'μBlock' but the name was later changed to 'uBlock' to avoid confusion as to how the Greek letter μ (Mu/Micro) in 'μBlock' should be pronounced. UBlock Origin is actively developed and maintained by its creator and lead developer Raymond Hill. uBlock Origin's stated purpose is to give users the means to enforce their own (content-filtering) choices. uBlock Origin has received praise from technology websites and is reported to be much less memory-intensive than other extensions with similar functionality. The extension is available for Chrome, Chromium, Edge, Firefox, Opera, Pale Moon, as well as versions of Safari prior to 13.

If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.UBlock Origin ( / ˈ j uː b l ɒ k/ ' YOO-block' ) is a free and open-source browser extension for content filtering, including ad blocking. Yet, even after adding Fanboy's two extra lists, hpHosts’s Ad and tracking servers, uBlock Origin still has a lower memory footprint than other very popular blockers out there.Īlso, be aware that selecting some of these extra lists may lead to higher likelihood of web site breakage - especially those lists which are normally used as hosts file. 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. Usage: The big power button in the popup is to permanently disable/enable uBlock for the current web site. An efficient blocker: Fast, potent and lean, and yet can load and enforce thousands more filters than other popular blockers out there.
