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.

- (2025-07-04) Vanessa Rubio: Once they fully stopped and shut down the original uBlock Origin i moved onto this one. This lite version is good and it does the job for what I need. Thank you for recreating what was the perfect ad blocker.
- (2025-07-04) MehZehLee: Does what Ublock Origin did before Google shut it down. Throws some false positives but blocks ads, which is all I want it to do
- (2025-07-03) jj: works WONDERFULLY. I was originally skeptical about using it since I have never used an ad blocker before, but after a recent situation with malicious ads I decided to search for a good ad blocker. This one works miracles! Not only are the malicious ads gone that I was worried about but Youtube seems to have no more ads for me as well. 10/10, especially for a free browser!
- (2025-07-03) Lamonte Robinson: Actually worked perfectly for a site that had HEAVY ads on it plus adblocker detection 10/10 rating!
- (2025-07-02) FD “GodofCarrots” FD: It's kind of disgusting how far Google goes to "protect" their users when in reality it's simply a fight for their bottom line. Thank you for such a dedicated team!
- (2025-07-01) Lazy Ass Gamer: Yeah Youtube really did a number and blocked this extension from working today, we need an update to slap on their faces. Update: Looks like it's working against YT again! Thank you DEVS!!!
- (2025-06-30) Pavan Gundu: A must install extension for today's world of internet browsing.
- (2025-06-30) DebtAndTaxes: Breaks chrome sometimes but works to get around anything anywhere.
- (2025-06-29) Luna Serena: This ad blocker is amazing!! It can block ads and other annoyances that other ad blockers cannot block or detect.. it's highly customizable, works on every website, even on youtube.. thank you, really thank you, for making our lives easier 💚 a big hug from Italy 🇮🇹
- (2025-06-28) Joey Cerda: works
- (2025-06-26) Pavel Sedlak: As unfortunate as it is from Chrome side to limit the extension abilities which resulted in need of Lite version, gorhill's work is outstanding, and for me uBlock Origin Lite covers all my needs and works very well for me, great work and thanks!
- (2025-06-25) Carl Dorio: June 2025 The score just mean it's not work for YouTube actually Don't work on YouTube Playlists. Probably YouTube have the eyes on this extension and will do all for never will work. Not sure the developer can do something, because YouTube is a lot bigger that him. And YouTube (well Alphabet witch own Google too and a lot of other, what we call monopoly) make billion of money with ads.
- (2025-06-25) Bryans Alejandro: doesnt work for twitch
- (2025-06-24) CompuMaster: Thank you!
- (2025-06-22) Spartan: It doesn't have an option to import your whitelisted websites. You have to do it one by one upon each visit if you don't want a particular website from being blocked.
- (2025-06-22) Jay R.: I believe highly in Ad Blockers, specifically on user-content sites like YouTube where they're just hosting the content and make money off those who create it, without proper restitution to those creators. If the actual content creators, who bring BILLIONS of monthly views, have to go outside YouTube to places like Patreon and Nebula, in order to make a decent wage for the 8+ hours they put into a video, then YouTube doesn't deserve the ridiculous amount of ad revenue they get off of them. Same for wiki and news-like sites that spam dozens of advertisements but, in reality, take very little actual effort and money on the back-end to operate (I host several) and still rely on user content (mostly free) to exist. That said, these sites, especially YouTube, constantly fight against these ad-blockers because they're greedy buggers. Advertising is the biggest scam anyway, especially with things like TV where you pay $100's of dollars just for them to deliver it to your home (I mean, aren't the ads supposed to pay for the shows?)... With fewer and fewer ad-blockers on the market, it gets easier and easier for sites like YouTube to figure out how to get around them. It's been several weeks now since the last YouTube update broke most of the existing ad-blockers. While "uBlock Origin Lite" stopped working, just like the rest of the ad-blockers, it was one of the first ones back up and blocking. You just had to remove and reinstall to get it back to working. That's why I still use it, and why it's getting 5 stars from me. Sure, it's missing several options that "uBlock Origin" had, but since the non-lite version has been removed by Google for "violations"... (eyeroll) ...This is our best option.

- (2025-06-21) Tj Tj: As of 6/21/25, videos are taking a while to load, with the "experiencing interruptions? find out why" pop-up appearing. After a couple of seconds, the video does play without ads as usual, but I thought it would be important to mention in case this is something that can be fixed.
- (2025-06-21) J J: Update: UBO Lite breaks sports website SI.com UBlock Origin Lite isn't anywhere near as effective as UBO, however, given the new MV3 rules UBOLite works very well and seems to work as well if not better than Ghostery or Adguard. Now UBO Lite has an element zapper to block those other pesky ads manually, it didn't have that recently. I'll keep this over any of the other adblockers.
- (2025-06-20) Seth Hernandez: youtube works. idk why the origin one was blocked. but this is a fine substitute.
- (2025-06-20) crx nineseveneight: Works with youtube (the only reason to install it) but otherwise lets a lot of ads through. Also, can't right click and block element. Very limited.
- (2025-06-19) BO: Works pretty dang well for being the Lite version and having to be changed because of Google trying to strong-arm their weight around.
- (2025-06-18) Dai Wen: Work well with YouTube
- (2025-06-18) Tim Holloway: Works perfectly. Maybe better than the original though sometimes I miss the ability to customize filters so I can block the clickable cards at the end of YouTube videos. I only realized today that setting it to Complete instead of Optimal was slowing down web browsing quite a lot. Now I'm so grateful for a speedy Chromebook that I wanted to come show a little love for the most valuable extension I run on Chrome. I think uBlock Origin Lite actually allows your browser to run faster than the classic, discontinued extension did, probably due to the simplification of its design.
- (2025-06-15) Rick Hustwit: Fpr YouTube, remove the old one and re-install it. Good as gold.
- (2025-06-15) Aivar krutoi: Youtube tells me stop using this app, so I can't watch videos on it with this app active...this never happened before. As of June 15 the problem with Youtube seems to be solved for now.
- (2025-06-14) DreamMoMo: IS GOOD APP
- (2025-06-11) Josh Stallard: Stopped working for YouTube but all you have to do is remove the extension and add it back to the browser.
- (2025-06-11) Renzo Morini: no longer working for YT, but hey its no fault of the dev but Google
- (2025-06-11) Mohammed Voneza: No longer work for YT
- (2025-06-11) Kevin: [WORKING WORKAROUND] Go to google and look up "Here's a working Youtube adblocker (for when uBlock, etc fall over)", click on the first result that should take you to reddit, once there you will see a post by u/damnThosePeskyAds explaining step by step. It's only 3 steps, it's quick and easy and works 99% of the time blocking ads and shorts. (with the exception of age restricted videos or videos with embedding disabled) It's working as of 06/11/25. RIP ublock origin, the lite version just has nothing on the original. EDIT: Just wanted to clarify the project is called goodtube, you can find the updated script on their github.
- (2025-06-11) Kolt Madden: If you want a bearable experience, put this in basic mode and then turn on Adguard. AdPocalypse 2 is coming, and get ready, because it's about to get whole lot shittier.
- (2025-06-11) Rohit Sarkar: not working for youtube ads
- (2025-06-10) E.W: No longer works on spotify or youtube.
- (2025-06-10) Dylan: please fix the youtube problem. You're the only thing standing between pleasant viewing and an ad every other minute.
- (2025-06-10) Nick Schmidt: fix it already lol. You know 9 out of 10 of us are using this for YouTube and it currently doesnt work. Update it or come out and say you're taking the L.
- (2025-06-10) zipmiX: 4/5 Because it works everywhere just fine, except youtube where they give the message "looks like you are using adblock". Hoping for a fix.

- (2025-06-10) Marc Sacriz: please make this function on youtube again. youtube detects this and im forced to disable it on that website
- (2025-06-10) Joseph Renard: The one and only ad blocker I use. It blocks all YouTube ads for a smooth uninterrupted viewing experience. Works great on all websites. I haven't found a site it doesn't work on yet.
- (2025-06-10) PokerusFreak: works okay. doesnt block as many ads as Ublock Origin did but at least its still functional.... for now. It has started recently being flagged by Youtube, so eventually I will probably have to swap unless they do a significant update. having come from the first Ublock Origin, it feels really lackluster, but since Google isnt allowing us to keep using UbO I will suffer with this until a better option becomes available or it gets fully blocked by Youtube
- (2025-06-10) Viktor Costa: One of the best......... sadly this feature is struggling against yt ads......... we need more devs to help Mr. Hill work on his project, let's make this this feature a safe haven for ppl who struggle against ads.
