Image from store uBlock Origin Lite

Description from store 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.

(2025-09-15) Anne Adorno: Thanks Google for blocking uBlock Origin. Time to move to Firefox
(2025-09-15) Sergei Letunovski: Google sucks balls
(2025-09-15) Thewaterspirit57: This stupid extension is honestly more frustrating to use than the original :/ Wanna filter ONE thing that appears across everywhere? you know, like the STUPID MEANINGLESS NONSENSE DRIVEN PEICE OF JUNK Grok thing on Twitter? YEAH NOPE! spend waaaay to long trying to filter that so you never have such a stupid AI explain a post that needs no explanation :P No matter how slowly you move the filter slider, the thing won't ever select the thing you want, maybe only two things or everything. you literally have to go through the little filter selection console just to find that one thing. Until this is fixed, I'm not gonna change my review. You can't even just use a packaged version of Ublock origin (the better one) on chrome, or anything under manifest 3.0
(2025-09-14) Arthur Lee: The old uBlock Origin is better than this one.
(2025-09-14) boomkittyFX: needs an update since stuff is getting through again, because google hasn't thought big brain and make the ad count before it shows so they still make money and we can still block ads
(2025-09-12) Yves S: Started getting : Experiencing Interruptions pop ups again this morning along with 3-5 seconds delays at the beginning of each videos. Been running flawlessly until then.
(2025-09-12) Janne Vuori: When I do a Google search in Chrome's incognito mode, I always get the text "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot". Except if I change "Allow this extension to read and change all your data on websites you visit" to "On click".
(2025-09-12) Google User: Grossly inferior to the full version. Might as well switch to Ghostery or Adguard if you want to stay with a Chromium browser or switch to Edge which still allows full uBlock and blocks YouTube ads. Otherwise, ditch Chromium browsers and move to a Chromium fork to buy you some time before MV3 becomes the norm. The end.
(2025-09-11) Noah El. S: Extremely efficient and quick to use.
(2025-09-11) Trent Isaacson: It seems to be able to block individual elements, though that filter list is not viewable or exportable, and I can't import a filter list, so this is pretty critical functionality that is missing and that's a big part of why I used the original uBO
(2025-09-11) Brad Bradley: Not as good as previous version which Chrome nerfed. Blocks almost every link in newsletters which is great if that's what you want but rubbish for those like me who want to open those links and have to keep clicking extra buttons to proceed.
(2025-09-11) Sergiu Jomiru: Top !
(2025-09-10) Aslan Khamzapur: Whenever I try to use it in incognito, it gives me the "Our systems have detected unusual traffic from your computer network." captcha
(2025-09-10) Oceans777: Easily & effectively configurable & protecting in minutes, Element Zapper!! Simple slider from off - basic - complete protection in Chrome. Rarely interferes with legit sites and if it does think before bypassing but easily done (slider). All of the tested & proven lists and tools in one stop. Zero nags ads garbage. None of AdBlocks juvenile endless begging. Common-sense powerful customization, a complete guide with why, where, when not just how. Evil thrives. Stop feeding it. uBlock it.
(2025-09-10) phuongzzz: One of the best extension ever made
(2025-09-09) BeastKat91: Google, please take some notes from the wonderful devs at ublock. I should not have to use third party software (even if it's incredible) to make your web browser that much more usable. I cannot switch my browser because I have a Chromebook, but if I had a PC I would switch to Firefox in a heartbeat! Big yikes for Chrome...
(2025-09-09) Alexander MacGregor: An awesome ad-blocker. It stood strong when faced with the wrath of an angry corporation, and told them "Go to hell, Abstergo." Don't think that I am committing an act of overreach by comparing Google to the Assassin's Creed universe; they share the same well-paid evil, the outstanding propaganda department, the same amoral and griping, grudging nature. For the sake of all of us, please download this; you too can fight back against corporate tyranny, from the comfort of your own home.
(2025-09-09) John Cross: please help it's no longer working
(2025-09-09) Aaron Henderson: it's good but it stopped working today (sept 8, 2025)
(2025-09-08) John: This isnt working
(2025-09-08) Graham Kerr: Quite good
(2025-09-07) Yahrite Fohb: Works ok but where the hell is the custom filters from element zapper etc? Nothing in the dashboard.
(2025-09-07) Marc Wegkamp: Love uBlock. it is the only thing stopping me from shifting browsers
(2025-09-07) Ariful Islam: Very strange. It's somehow working now. It was not working previously but now it's working. I think google may read all the previous reviews. By the way, appreciate google for giving priority to user's need
(2025-09-06) Paul Miller: Works
(2025-09-06) Nils Steyaert (Spey_Phantom): as of today, its not working anymore, im getting the youtube anti-ad blocker screen again.
(2025-09-06) Metehan Ataman: Not as good as the previous one, but it gets the job done, prefer if you could customize the filters more. though as of right now youtube now detects it.
(2025-09-05) Renz: Awesome. I can now block those pop-up ads on corn sites.
(2025-09-04) Francesco Amendola: Indispensable, works just as good as UBlock classic
(2025-09-04) Vladimir Borduja: Great extension, blocks everything annoying to me, thx to the owner :pray:
(2025-09-03) Frank Conijn: Not as good as the original version. Among other things, with the original one could disable the extension per site.
(2025-09-02) long Vu: F you if you didn't vote for trump and on here praising ublock. Alphabets, chrome, youtube are all complicit with the democrat to spread fake news, allow open borders and crimes. I will go out of my way to make sure none of these looney liberal democrat backed company make a single cent from me. So F8k your DEI ESG rainbow alphabets looney tune. I hate hypocrite like you, supporting democrats and on here using adblocker.
(2025-09-02) Vince Dugar: Outstanding extension! The developer/team is very talented!
(2025-08-29) kiệt hoàng: Nice extensions. Great for dev !
(2025-08-29) Killua Zaoldyeck: Taken as trojan ELF[MiraiDab] by AVG.
(2025-08-29) Johan Buelens: The latest update causes some of the more popular virusscanning suites to flag one of the files as a possible ELF:Mirai-DAB[Trj] this is an Indexed MetaData file that is called _ruleset6. A ruleset that give the add-on it's list of blocked websites. It is a false Possitive and can be ignored or flagged in your virusscanner as a false possitive. The hexdump of the file also confirms this as it starts with "2D 2D 2D 2D" not the "7F 45 4C 46" that a true ELF trojan would always use. You can flag the file as safe should you get a possitive reading. Hopefully people looking up this issue and land here will find this usefull.
(2025-08-29) TinyLivi: Its good, better than most other ad blocks but both AVG and Norton are detecting ELF:Mirai-DAB[Trj] after the latest update. Not sure if this is a false positive?
(2025-08-29) AngelMike Dotcom: The extension failed to load properly. It might not be able to intercept network request Dunno what that is about one of a sudden. Never had any problems with it till it sayingthis
(2025-08-29) EVANSON HAKEEM: It's not as good as the original, but it's a solid 95% of the way there. It gets the job done.
(2025-08-28) Eugene: google destroyed many good anti spam extencions
(2025-08-28) Pranto Roy: good and helpful extension
(2025-08-27) Tom: Interferes with multi factor authentication systems on certain websites of financial institutions. Would make it impossible to login without disabling the extension.
(2025-08-27) Imrane B: Works great. I will NEVER pay for youtube "premium"
(2025-08-27) Cameron Abueg: Best thing ever, try on spotify and you will be AMAZEDDDDD!!!!!
(2025-08-26) Reese Kollman: Some popups would show up regardless of other ad blockers. This is the only one I found that works for all popups.
(2025-08-26) Netanel Ofri: Missing the ability to configure a list of whitelisted domains where blocking is disabled. Have to manually turn off blocking per website.
(2025-08-25) nayak: Best I have ever seen till now.
(2025-08-24) W: Keep fighting the good fight
(2025-08-24) Edwin Kim: Simply awesome, especially when it's free.
(2025-08-23) Redwan Islam: Ah man , Next thing I know its shut down
