i guess its firefox or vivaldi, shove ads in my face ill just not use the internet, its just ai rot made by 8yr olds anyways

Google User 2025-10-03

Google has removed hundreds of Mv2 extensions and not because they are the best at what they do. Brave is removing them too. Use uBlock Lite or Adguard. The end.

Nope Nope Nope 2025-10-02

Bye Bye Chrome <3 Brave here I come xD

Ernest Crus 2025-10-01

Google removed it because it was the best.

So: YouTube gives me trouble for having an ad-blocker on. And since I realize they won't allow this, and I had installed this only for YouTube, I remove it from extensions. What happens is: YouTube ads continue to be blocked, and YT keeps giving me trouble. Solved only upon reinstalling this extensions, and disabling ads on YT. You should code it, I'd say, so that when it is uninistalled all its effects are removed with it. BY THE WAY: this is still available on the Vivaldi Browser: a browser built on Chromium, with full access to the Chrome Web Store, but much unlike Chrome otherwise.

Alexander Stormdahl 2025-09-28

You guys can't download uBlock or what's up? I downloaded it just now and it works fine..

Josh Michael 2025-09-27

Fk you Google..

Trystan le Fey 2025-09-24

And alas, one of the few things that makes browsing the internet tolerable is gone. Shame on you Google. You are lucky that using Brave on my Chromebook is more trouble than its worth.

How to reinstall Unblock Origin and get the most updated one: 1. Go to https://github.com/gorhill/uBlock/releases and download the most update chromium.zip 2. Unzip the folder inside 3. Go to 'manage extensions' 4. On the top right you'll see 'Load unpacked', select it 5. Then select that Ublock0.chromium, and there now you have Ublock again. And if you get any Manifest errors, you can check out this website that can help you get around it: https://winaero.com/how-to-restore-manifest-v2-and-ublock-origin-in-google-chrome-139/

yuck fou! google! is this your "best practice"?

Jonathan Almanza 2025-09-21

welp this was the best ad blocker sad to see it gone

Ray 2025-09-18

greatest extension out there when it still was able to download, sucks that Google is greedy b and wants people to watch ads every 5 seconds. This extension made the internet safer, keeping people away from scams that ads casually give out. RIP, best ad blocker to ever exist

Darryl Collins 2025-09-18

works on FF, and with that I have begun my exodus from chrome

Zackary Rethati 2025-09-18

The only extension that made Chrome worth using

Srijan Sarkar 2025-09-18

The best browser extension ever.

RedLabs Entertainment 2025-09-17

My browser rides shotgun with this. Essential for how the current state of internet is.

Mauro Avello Revenga 2025-09-17

Best out there, but you have to look for it now...

Riz Warner 2025-09-17

F O O K GOOGLE FOR REMOVING THIS AWESOME ADDON!

doot doot 2025-09-14

Made internet usable. See you all on Firefox (hopefully)

Daniel Hawkins 2025-09-14

One of the best extensions ever, and shame on Google for killing it. Looking to find another browser now.

Energite Knight 2025-09-13

Thanks uBlock Origin, it was great while it lasted. Too bad V2 extensions are permanently axed starting from Chrome Version 140+, RIP.

Procos 2025-09-13

Great ad blocker, see you in firefox

Rowller Stazmatov 2025-09-13

An adblocker that worked so well the corpo's killed it because they were loosing too much money.

Zach Rainbow (Zachary Whiteman) 2025-09-12

I am so sad to see it go! As of 20 minutes ago google chrome will no longer let me force Manifest V2 Extensions. I am formally switching to Floorp (A FireFox based browser...) It is really a shame.

Can Chan Koop Man 2025-09-12

Probably the single best ad blocker in existence

Matt 2025-09-10

So sad that Google is blocking it

axo tio 2025-09-10

uBlock Origin unsupported Info: https://github.com/uBlockOrigin/uBlock-issues/wiki/About-Google-Chrome's-%22This-extension-may-soon-no-longer-be-supported%22 TLDR: Install uBlock Origin Lite

RIP to the #1 AdBlocker on Chrome

June Change 2025-09-09

awesome

aubbers 2025-09-09

Best adblock ever. left chrome to continue use.

Alex L 2025-09-08

Great app. Switched from chrome just to keep it.

Devansh Arora 2025-09-07

why did u guys remove ubo why?!!!!!!!!!!!!!!!!!!!!!!!!!!!

Sam J. Pepper 2025-09-07

Good bye. The workarounds and extension shortcuts don't work now. Firefox is too slow for me, eventually they'll move to MV3. Developer of uBlock says they won't support Chromium based browsers in the future. It's sad how Google is normalizing ads and adware.

Damien Pfohl 2025-09-07

You just have to disable and enable some fast flags to use this actually amazing extension for god knows how long

Hassan 2025-09-07

Switching off of Chrome because Google and Youtube are run by slimey jeets that hate ad-blockers. KYS Google.

Shannon S 2025-09-06

The internet is unusable without uBlock Origin. Even the workaround to use it on Chrome is no longer available to be. Chrome was already on thin ice with me. I'll be switching to Firefox and would recommend everyone else still on Chrome change browsers as well. Free Palestine

Anne Adorno 2025-09-06

Goodbye Chrome/ium. I don't appreciate you telling me which extensions I can run in my browser. I also don't appreciate not being able to choose which tabs can be active and which cannot. So much resource consumption.

Gab 2025-09-05

I don't know what I would do without this extension, it's basically required nowadays

Julien 2025-09-05

Youtube's blocking it again.

Hamu Taro 2025-09-05

doesn't work on Youtube, update please

Gordan 2025-09-05

uBlock Origin is more worthy than Chrome altogether. I'm changing browser because of this

Dylan the brand slayer Mulveiny 2025-09-05

Google is scum for removing this. People don't want to be forced to view ads. Especially when half of them are malware. I genuinely think people should start a class action lawsuit, because this is a blatant violation of anti-trust laws.

Turdley Brown 2025-09-05

Great job Google. No wonder you dropped your "Don't be evil" motto. You've finally forced me to go back to Firefox. We will not accept your censorship or forcing ads on us. Restore Ublock Origin or suffer the consequences.

FatheredPuma81 2025-09-05

On good browser: Ublock Origin - GET - "Switch to Chrome to install extensions and themes INSTALL CHROME" On Chrome: "LOLOLOLOLOL NO"
