uBlock Origin is a free and open-source, cross-platform browser extension for content-filtering, including ad-blocking. The extension is available for several browsers: Chrome, Chromium, Edge, Firefox, Opera, Pale Moon, as well as versions of Safari prior to 13. uBlock Origin has received praise from technology websites and is reported to be much less memory-intensive than other extensions with similar functionality. uBlock Origin’s stated purpose is to give users the means to enforce their own choices. As of 2021, uBlock Origin is still actively developed and maintained by its creator and lead developer Raymond Hill.
