--- title: uBlock Origin canonical: https://saasranked.com/software/ublock-origin/ category: Ad Blockers points: 95 rank: 1 of 12 facts_checked: 2026-10-08 --- # uBlock Origin Free, open-source blocker for ads, trackers and malware sites. The full add-on runs on Firefox, Edge and Opera; Chrome gets a Lite edition. 95 points out of 100. #1 of 12 ad blockers. Vendor: Raymond Hill. Website: https://github.com/gorhill/uBlock - uBlock Origin is free, and the project says it seeks no donations [1]. - The full add-on is listed for Firefox (desktop and Android), Edge and Opera; it left the Chrome Web Store on 31 August 2026 [1][5][6][7]. - uBlock Origin Lite, built on Manifest V3, is listed for Chrome, Edge, Firefox and Safari, and needs iOS 18.5 or later on iPhone and iPad [3][4]. - By default it blocks ads, trackers and malware sites using EasyList, EasyPrivacy, Peter Lowe's list and an Online Malicious URL Blocklist [1]. - Source code is public under GPL-3.0 [1]. Verdict: uBlock Origin suits people who want a free, open-source blocker with their own filter rules and no data collection [1][2][9][10]. The full add-on runs on Firefox, Edge and Opera, while Chrome users get the Lite edition built for Manifest V3 [1][3]. The catch: Lite is a pared-down version, the full add-on left the Chrome Web Store on 31 August 2026, and the blocker works only inside browsers [1][8]. Best for: People who want a free, open-source blocker with their own filter rules. Status: The full uBlock Origin was removed from the Chrome Web Store on 31 August 2026; on Chrome the project now offers uBlock Origin Lite [1][3]. ## Points | Criterion | Line | Value | Points | Note | |---|---|---|---|---| | Where it blocks | Windows browsers | Chrome, Edge, Firefox, Opera | 12/12 | The full add-on is listed for Firefox, Edge and Opera; Chrome lists uBO Lite [1][3][5][6][7]. | | Where it blocks | Blocks outside the browser | No | 0/5 | The project describes uBO as a blocker for Chromium and Firefox; its README lists no Windows app or system-wide DNS setting [1]. | | Where it blocks | Phone protection | iOS, Android | 6/6 | Android: the full add-on runs in Firefox for Android. iOS: uBO Lite for Safari on iPhone and iPad, free on the App Store [1][4][5]. | | Blocking | Still works in Chrome after Manifest V2 | Yes | 4/4 | On Chrome the project offers uBO Lite, a named Lite edition based on the Manifest V3 API; the full add-on is Manifest V2 [3][8]. | | Blocking | Your own block rules | Yes | 7/7 | My filters takes your own rules; the Filter lists pane imports third-party lists by URL.
