uBlock Origin
Extension Actions
- Live on Store
มาแล้ว! โปรแกรมบล็อกโฆษณาได้อย่างมีประสิทธิภาพ โดยที่ไม่กินซีพียูหรือแรม
IMPORTANT: uBlock Origin is completely unrelated to the site "ublock.org".
CHANGELOG: https://github.com/gorhill/uBlock/releases
***
An efficient blocker: easy on memory and CPU footprint, and yet can load and enforce thousands more filters than other popular blockers out there.
Usage: The big power button in the popup is to permanently disable/enable uBlock Origin for the current web site. It applies to the current web site only, it is not a global power button.
***
Flexible, it's more than an "ad blocker": it can also read and create filters from hosts files.
Out of the box, these lists of filters are loaded and enforced:
- uBO filter lists
- EasyList (ads)
- EasyPrivacy (tracking)
- Peter Lowe's Blocklist
- Online Malicious URL Blocklist
More lists are available for you to select if you wish:
- EasyList Cookie List
- Fanboy's Annoyance List
- AdGuard Annoyances
- Dan Pollock’s hosts file
- And many others
Also, be aware that selecting some of these extra lists may lead to higher likelihood of web site breakage -- especially those lists which are normally used as hosts file.
***
Free.
Open source with public license (GPLv3)
For users by users.
If ever you really do want to contribute something, think about the people working hard to maintain the filter lists you are using, which were made available to use by all for free.

- Google controls and monitors E V E R Y T H I N G . Chrome sucks.
- Brian
- Looks like my Vivaldi browser doesn't support it now too.
- Sasha
- So many awesome MV2 extensions — many are not adblockers have been removed now by Chrome in version 150.x. I tried the workaround method, it's a chore to perform every few hours. Worst of all, it's temporary. Surprisingly, the MV3 extensions of Adguard & uBlock Lite are just as good as uBlock Origin MV2 in my experience so I'm using them now. uBlock developers says to switch to Lite or another browser. RIP to all the great MV2 extensions that were once on Chrome! Otherwise Brave still has MV2 extensions like uBlock Origin.

- so good, chrome wants it gone
- Ali Ebrahiminejad
- I'm switching browser. Don't use Chrome-based browsers, value your freedom!
- Leandro de Assis
- hey google, don't touch on my best extension.
- Google User
- OMG. Google FINALLY did it. uBlock 1.72 worked fine until today. Google killed the only workaround to keep uBlock in Chrome. Now, I am switching browsers. So sad. July 1, 2026 will go down in history! Edit: I found a temp workaround, but it's complex!

- This is a test review.

- Super!

- Version updated to 1.71. Interestingly, with SuperAdblock Test, uBlock scored lower than MV3 Aguard. And unlike Adguard, uBlock (this version) doesn't block cookie annoyance banners from the CBC News site despite adding it the filter list. And as of March 12 this extension is still supported on Chrome. I don't understand all the whining. Everyone should be grateful developers are still maintaining it instead of yanking it.

- This is the best extension on the Chrome Store. It's so good that Google had to allegedly get creative and change the Material Design format to make uBlock Origin not work anymore as designed, forcing them to create a stripped down version as a replacement.
- Abebe Mamo
- we are facing experience interruptions on youtube can you fix that pls
- The Heretic (Snordelhans)
- Greatest browser extension ever made in the history of mankind. Nothing comes even close.
- Tom Sinex
- Absolutely do not use this extension. If you ever need help with anything and report it on their github the mods there will throw a hissyfit and ban you. They won't even acknowledge clear things you put in front of their face, absolutely pathetic. Some are good, but you're better off just finding another extension.

- Maverynthia Crowinthas
- Great, however Google has decided to block adblockers and things like that by saying they don't follow their "best practices". If you already got it, good. Else you should switch to a different browser. (Not Brave)

- Can Güler
- Stopped blocking ads on Youtube for almost a month now. Every time I click on a video ads start loading and they won't go away until I reload the page. When are you going to fix it?

- 羽水
- Shame on greedy Chrome for disabling this wonderful extension. I will keep on using it any way I can, and if I can't anymore, I'll switch to a different browser. uBlock rules !!!
- Split Soul
- one of the best extensions for the web with plenty of filters and custom filters as well screw google and ublock lite if you want to block things still and still have extension support just use tor firefox brave and palemoon google sucks is too intrusive and caters to sites that makes false claims about extensions that clearly work well and gets them falsely removed as "malware"
- kotik v o4kax
- One of the best adblockers ever, though twitch ads get through sometimes
