uBlock Origin Lite
Extension Actions
- Extension status: Featured
An efficient content blocker. Blocks ads, trackers, miners, and more immediately upon installation.
uBO Lite (uBOL) is an efficient MV3-based content blocker.
The default ruleset corresponds to uBlock Origin's default filterset:
- uBlock Origin's built-in filter lists
- EasyList
- EasyPrivacy
- Peter Lowe’s Ad and tracking server list
You can enable more rulesets by visiting the options page -- click the _Cogs_ icon in the popup panel.
uBOL is entirely declarative, meaning there is no need for a permanent uBOL process for the filtering to occur, and CSS/JS injection-based content filtering is performed reliably by the browser itself rather than by the extension. This means that uBOL itself does not consume CPU/memory resources while content blocking is ongoing -- uBOL's service worker process is required _only_ when you interact with the popup panel or the option pages.

- It's a fairly good adblock, however it is dysfunctional on spotify, hence the missing star.
- Shahanara Begum Hena
- uBlock Origin Lite is a fantastic lightweight ad blocker that's perfect for modern browsers like Chrome and Edge. As a streamlined version of the legendary uBlock Origin, it skips the advanced scripting features to comply with Manifest V3 rules, but it still crushes ads, trackers, and pop-ups with impressive efficiency—using just a fraction of the resources of heavier alternatives. In my testing, it blocked intrusive YouTube ads, sponsored social media posts, and creepy trackers on news sites without slowing down page loads or draining battery life. The interface is dead simple: enable it, pick filter lists (like EasyList or EasyPrivacy), and forget it. No unnecessary permissions, no paywalls, and it's 100% open-source and free.

- One of the best and needed extension
- Sean Carey
- Works perfectly—no ads, no complaints.
- Elbert
- Despite being the Lite version, it is still effective. Together with Privacy Badger, it provides reasonable protection against tracking in Chrome.
- Grogro Milazzo
- It still works and is useful despite its Lite condition. The missing star is due to its non-functionality on spotify.
- seaspirit
- Can custom filters include a timestamp display (like creation date) and a field for adding notes? After a while,it's easy to forget what the filter actually does

- Micx
- Words cannot describe how this extensioin makes me feel. My life changed the day I found out this existed. Other adblockers (especially the paid ones) shouldn't exist because this is just better. This is so good it does and the foremost what it's supposed to do, BLOCK ANNOYING ADS and no gimmicks. Thebest part is that IT IS COMPLETELY FREE, no subscription. 2 years or so going strong, I can't imagine using chrome without it. Luckily it is now available on Safari as well. To the team or whoever it is at UBlock, I just want to say a massive thank you, I love you all.

- Works as good as the original. I don't know how other blockers even exist. This is the only one I have found always blocks everything. And as a bonus, it is so easy to delete any page element.

- This is a great extension😍
- YEO FENG KAI Moe
- This is a great extension. When my Google Chrome can't use Ublock Origin, I can use Ublock Origin Lite. While it's not as feature-rich as the original, it's sufficient. It not only blocks annoying online ads but also directly blocks problematic websites. That's why I give it a perfect score.

- This is actually a great adblocker, I never get ads on Youtube and even on Hulu and other streaming platforms. on top of that its a Chrome Extension so you don't have to deal with out of browser download. this is one of the best free ones I have experienced. I recommend it.
- Tetley
- Great addon! Unfortunately YouTube must have done something today that somewhat limits this addon. Livestreams will not start with this running, but if you disable it the livestream will start. You can reenable it after and it seems to work. But this has to be done every time you start watching a livestream. This is my experience that started today, may not be affecting others the same. Edit: It does not seem happen every time. It seems hit and miss as to whether it will prevent a livestream from starting.

- i love this extension but recently it started to block another extension to re-enable to mini play button on youtube :( resetting ublock fixes it temporarily
