Opera browser required.
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 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:...
- This extension can access your data on all websites.
- This extension can access your data on some websites.
- This extension can manipulate privacy-related settings.
- This extension will add a panel to the sidebar.
- This extension can access your tabs and browsing activity.
- This extension can store an unlimited amount of client-side data.

Hi Greeting. I also get that annoying notification with Opera Developer version 135.0.5960.0, Every time it relaunches. I ended up every time delete uBlock Origin and reinstall, by bookmarking this page. Still worth the trouble! Thank you for the amazing app. I also use ublock DNS.

uBlock Origin Version 1.72.2 updated July 8 has been working fine for me in Opera One Windows 11.
Check your Opera Settings /Privacy & security /Privacy protection Block ads and surf the web up to three times faster is Off as per the image, highlighted in the red frame. My understanding is the setting is part of the Opera AdBlocker and You Tube detects it. - Bbovenbaas2 weeks ago
Since yesterday "This extension was turned off because it is no longer supported". YouTube has been terrorizing me with adds since.

@bovenbaas just wanted to share with you that this extension has been the only one to reliably reduce ads it takes a different approach can pretty much clicks the skip button for you but it also skips the video to the part when the skip button comes up so it's able to skip through the video so it's almost instantaneous it's able to skip through the ads. The name is "Autoskip for Youtube
Ads". Not much creativity in the name but it works good. I will go ahead and attach a screenshot of what it looks like in my Opera GX see what the icon and stuff looks like.

The same issue happens again at Youtube. I removed ublock origins, re-installed, re-launched Opera again. Still the problem is continueing.

I installed uBlock Origin Lite from the Chrome Web Store and it works fine on You Tube with Opera.

il faut désinstaller u block origin,puis le réinstaller,suivre la méthode de @mantapp
et il faut désactiver le bloqueur d' opera,utiliser uniquement u block origin et ça fonctionne parfaitement.
mais pour ça,il aurait fallu lire les commentaires au dessus....... et vous seriez dépanné !!

The ublock origin at the opera extension isn't updated, but it will be soon. If you can't wait, install the ublock lite from the chrome store into opera, that blocker was updated 5/30 and works.
