uBlock Origin Lite (uBOL) is a lightweight and efficient content blocker built on Manifest V3 technology. It blocks ads, trackers, and cryptocurrency miners immediately upon installation by using the trusted default filter lists from uBlock Origin, EasyList, EasyPrivacy, and Peter Lowe’s Ad servers.

Unlike traditional extensions, uBOL leverages the browser's declarative filtering capabilities to block unwanted content without running a continuous background process. This ensures minimal CPU and memory usage, as filtering is performed by the browser itself, and the extension's service worker only activates during user interaction with the popup or settings. Users can easily enable additional filter lists via the options page, tailoring their browsing protection effortlessly. uBlock Origin Lite combines powerful blocking effectiveness with optimal browser performance for a safer and faster web experience.

User reviews

uBlock Origin Lite is praised as an effective and popular ad blocker that historically updates quickly to counter YouTube's ad detection. However, multiple users report that as of June 2025, YouTube has detected and disabled the extension's ad blocking, causing videos to be blocked behind anti-adblock warnings. Some express frustration over the lack of control to disable blocking on certain sites. There are also isolated concerns about antivirus software falsely flagging the extension. Overall, users hope for an update to restore seamless functionality on YouTube.

Pros

Fast updates have historically restored functionality quickly after YouTube patches.
Highly recommended by users as one of the best ad blockers available.
Basic filtering mode allows some users to bypass YouTube's adblock detection.

Cons

Currently does not work on YouTube due to detection and blocking by the platform.
Users report YouTube showing anti-adblock messages and videos becoming unwatchable.
No option to completely disable ad blocking on specific sites, limiting user control.
Some users report security software flagging the extension as potentially unsafe or adware recently.

6월 11일 패치로 다시 작동되네요. (필터링 모드 '최적' 사용중) 영상 시작할때 약간의 버벅임이 있는데 보통은 잠깐일뿐이고 가끔 길어진다 싶으면 새로고침하면 되더군요.
