uBlock Origin (/ˈjuːblɒk/ YOO-blok[5]) is a free and open-source browser extension for content filtering, including ad blocking. The extension is available for Chrome, Chromium, Edge, Firefox, Brave, Opera, Pale Moon, as well as versions of Safari before 13.[6] uBlock Origin has received praise from technology websites and is reported to be much less memory-intensive than other extensions[7][8] with similar functionality.[9][10] uBlock Origin's stated purpose is to give users the means to enforce their own (content-filtering) choices.[11][12]

uBlock Origin is actively developed and maintained by its creator and lead developer Raymond Hill and the open source community.[1] As of October 2024, the Chrome version of uBlock Origin had over 40 million active users and the Firefox version had over 8 million active users.[13][14]
