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.

- If you can't bring yourself to stop using Chrome, after they limited how Ad Blockers work, this is by far the best option. Honestly though, Edge is unironically better than Chrome in 2026. It uses the same Chromium engine, but it receives far more love from Microsoft than Google gives Chrome, and they don't limit Ad Blockers so you're not forced to use the Lite versions. If you don't mind a more significant change in browsers, give Firefox a try.

- I have it set on "Optimal" filtering, and it silently makes the entire internet faster and less intrusive. I only realize how perfectly and silently this extension improves my life when I use a browser that does not have it installed.

- hutchmaster
- amazing ad blocker. Blocks ads on youtube and even hulu for me
- Jolan XBL
- Basic mode: Allows YouTube ads Optimal mode: YouTube detected it & delayed playback Complete mode: YouTube detected it & delayed playback even longer. Either Ad-blockers suck at blocking ads, or Google is spying on installed software & plug-ins.
- Александр Даниленко
- I didn't have a persistent need for adblock until one of the sites I frequent started loading full HD videos in place of static banners, basically eating all my traffic. With basic filtering enabled, I still see normal ads, but none of those abominations ever since. Will keep updated.

- osirisgothra (osirisgothra)
- Welp guess that tears it. There's no ad blocker that can stop unwanted page navigation or adblock-blockers. These extensions (ubo, abp, etc) all of them just block the old embedded ads. I can block those without an adblocker these days with stylus or similar. I guess the ad people won. Its not like there's a group of idiots that fall for this. And I am sure glad I am not a moron who gives in to ad walls and pay walls because I don't know any better and will open my wallet for anyone and everyone.
