Description from store
uBO Lite (uBOL) is a *permission-less* 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.
uBOL does not require broad "read and modify data" permission at install time, hence its limited capabilities out of the box compared to uBlock Origin or other content blockers requiring broad "read and modify data" permissions at install time.
However, uBOL allows you to *explicitly* grant extended permissions on specific sites of your choice so that it can better filter on those sites using cosmetic filtering and scriptlet injections.
To grant extended permissions on a given site, open the popup panel and pick a higher filtering mode such as Optimal or Complete.
The browser will then warn you about the effects of granting the additional permissions requested by the extension on the current site, and you will have to tell the browser whether you accept or decline the request.
If you accept uBOL's request for additional permissions on the current site, it will be able to better filter content for the current site.
You can set the default filtering mode from uBOL's options page. If you pick the Optimal or Complete mode as the default one, you will need to grant uBOL the permission to read and modify data on all websites.

- (2024-07-31) J J: UBO Light is the new MV3 new rules restriction by Google whereas UBO is the much better one that uses MV2. Google is limiting new rules per extension at 30K, which means UBOL will be a lot less effective that UBO going forward w/o the ability to block elements or ad any filters. This is a Google restriction and not a UBO one. UBOL works fine when I tested vs UBO but I want the added filters and element removal. I'm planning to use Firefox over Chrome because I hate Google.
- (2023-12-14) neko kuro: Chromeが広告ブロッカー締め出し方向に行ってるので将来的2025辺り以降？には現在の広告ブロッカー ほぼ使えなくなりuBLOCKはこのライト版しか使えなくなるらしいので導入しといて損はないです ただライト版ポリシーが違うのでフィルター追加や高機能な事はできないのでやはりブロック率は下がります。
- (2023-12-13) Othmar HANNY: Seit dem letzten Update (2023.12.4.1333) funktioniert die Erweiterung gut und sehr effizient. Hat bei mir die Standardversion uBlock Origin endgültig abgelöst. Sehr gute Arbeit!
- (2023-11-22) ralph liu: Awesome to have a super simple yet effective ad-blocker future proofed to work after the MV3 update. Really appreciate you guys!
- (2023-11-09) 0yuyuko: grateful uBlock Origin author I'm not sure if this is a new version developed by you. It's great. I hope it can block the ads on major websites.
- (2023-10-28) Dinesh Babu Vasudevan: Works Flawlessly..
- (2023-10-18) Thomas Anderson: Doesn't work at all.
- (2023-10-17) TheRealF148: Hey Raymond, I see that you're responding to these. First of all, I'd like to thank you for so much of what you do. Ads nowadays are extremely long and are outright wrong for the amount of time they take from us and our productivity. And when I say long, I'm referring to Youtube. Do you know what we can do about Youtube's new Adblock detection? Thanks
- (2023-10-11) Jaya Ang: UBO lite blocks pretty much all ads, and actually seems to manage to evade adblocker-detection a lot better than other web browsers like Ublock Origin
- (2023-09-20) sanek babos: очень нравится
- (2023-09-15) chun chun: Works well but a bit slow, i rather use another adblock extension and use both.
- (2023-09-03) freespirit: It seems to work for a week or 2 then bugs out, when you click on the icon everything is going haywire and I am unable to adjust anything because its moving so fast, I have no choice but to either turn it off or reinstall it, Have not seen a way to correct this bug other than uninstall and reinstall the entire extension ever week or so otherwise it's a good extension
- (2023-08-25) Malikul Akbar: based on MV3, quite good,
- (2023-08-22) Rob Kry (Rob): Unfortunately, uBlock Origin Lite V3 does not block all ads. Only normal uBlock Origin V2 works fine.
- (2023-07-27) CFD: What a bummer, no way to custom block unwanted & unblocked nuisance Ads or Elements on Websites/Webpage's... Otherwise, seems great & would be that much better if it actually had that feature built-in to it, much like other Ad Blockers.
- (2023-07-20) Lukáš Nagato: Funguje!!
- (2023-06-08) Chad Scribner: I'm curious as to when "Experimental" will be removed from the description. With the addition of EasyList's Annoyances and Cookie Notices, this seems nearly indistinguishable from uBO Heavy. Thanks for all the hard work!
- (2023-05-28) D. Smithee: All hail the Savior of the Internet, gorhill! This "experimental" MV3 version of UBO works extremely well.
- (2023-04-20) 下条朝人: フィルターが初めから入ってるやつしか使えないから、今はまだ微妙。
- (2023-04-13) Илья: Супер!
- (2023-03-25) Sergio Emir Rozo Díaz: Está genial aunque sería bueno que dejara seleccionar la publicidad a eliminar.
- (2023-03-22) Alan Sanchez: It doesn't not block ads for me
- (2023-03-07) Edmárcio Santos [ethomaz]: The simple look and strong blocking capabilities surprised me to the point I couldn't tell the difference from original uBlock Origins (I'm not a power user at all). I rater prefer this new appouch over the original... and it fell ligher in CPU and recourses use...amazing. Great job devs... Raymond you deserver all the praise you overdid again. Loving it.
- (2023-03-02) Chang Soo: Doesnt lite become useless since it doesnt have a custom list so you cant block sites that it doesnt pick up.
- (2023-03-01) Patrick: As good as the normal ublock origin. Blocks all ads on youtube/youtube music/twitch/etc. If you also got adguard home/pihole+unbound, then you are good to go. This lite version is faster and less resource heavy than the standard version.
- (2023-01-18) Jon N: A very good MV3 based adblocker. Three things missing: cookie notification prevention and social media annoyance filters, you know the twitter and facebook buttons. In the old extension I liked using the element hider and custom filters too. The cookie notification is the big one for me. Do people have to install a separate extension for that or would it be possible to implement it in MV3 uBOL? Thanks again for developing uBO lite!
- (2022-12-26) Atif Hussain: Working great. Would be great if we had the option to see websites that have received complete read permission in a single list and to manage them directly from the list. edit: the permissions are acting a little weird. After clicking UBO icon the extension receives full site permissions even in basic mode (this can be seen after hovering over the UBO icon, it says has access to site whereas without clicking the icon it says wants access to site).
- (2022-12-12) Dabi: Definitely feels lighter and simpler than the full uBlock. And it's nice how it allows the "Preload pages" setting. I'm glad that efficient ad blocking seems to be still possible under MV3. Might be not enough for power users, but for me it works great.
- (2022-12-07) Google User: Seems ok, not much of a difference compared to using just one extension, say Ghostery.
- (2022-12-06) Riley: One of the best ad blockers to ever exist. I highly recommend this to everyone who uses chrome.
- (2022-11-29) Google User: Is there anyway to force "complete" or "optimal" in the registry? Or maybe have it point to a config file like we did with the original?
- (2022-11-05) Dmytro PoRtvine: It is possible to add an operator :remove() ? Description does not match reality: - No cosmetic filtering (##) - No scriptlet injection (##+js) - No redirect= filters - No csp= filters - No removeparam= filters
- (2022-10-26) Renato Adesivagem: excelente. Bloqueou todos anúncios do Instagram.
- (2022-10-14) William Feely: Excellent in concept, but it appears to be flaky, not always killing YouTube ads. When checking the addon when it failed (I did give permission to modify youtube.com) it showed reddit.com which I previously browsed.
- (2022-10-11) Anjas Wahyu: make cosmetic filtering enabled pls
- (2022-09-29) René Stout: Een prima opvolger van de standaardversie. Knap werk!
- (2022-09-28) vasilis vita: works everywhere except youtube ... if only you could do something for it , I know it is difficult
- (2022-09-28) Simon Simon: Not as good as ublock origin and probably never will be, really sad. Gorhill does a great job for millions and millions of people, we can't thank you enough!
- (2022-09-28) Серж U: Включите, пожалуйста, возможность добавить свои правила для блокировки и фильтры. Спасибо.
- (2022-09-28) Steve Seguin: Sadly, YouTube ads aren't blocked for me with this extension -- I'm giving 5 stars with the consideration that this is still a bit of a 'preview', with the hopes it does manage to improve. I really appreciate the developer's efforts with MV3, like a lot, as migrating my own ext to MV3 is proving a nightmare.
- (2022-09-25) Laìcurè Levìarè: still the best and it is working well, I haven't tried with other sites but I can see it still blocks ads. Hoping to see, at least, the domain whitelist functionality.
- (2022-09-24) Jan Brodda: Works great and fulfills all my needs regarding adblocking without requiring any permissions!
