What Happened to uBlock Origin?
In early 2025, Chrome users began seeing messages that uBlock Origin had been disabled or was no longer supported. The root cause is Google’s rollout of Manifest V3, a new extension framework for Chrome.
Manifest V3 restricts how browser extensions interact with web content, especially ad blockers, making it impossible for uBlock Origin to function as before.
As a result, Google removed uBlock Origin from the Chrome Web Store and began automatically disabling it for users.
uBlock Origin Not Supported on Chrome
The message “uBlock Origin is no longer supported on Chrome” is now common for users. This is due to Chrome’s enforcement of Manifest V3, which blocks extensions built on the older Manifest V2 standard. uBlock Origin, which relied on Manifest V2 for its advanced filtering, cannot operate under the new restrictions.
uBlock Origin Turned Off in Chrome
Many users reported waking up to find uBlock Origin turned off automatically in Chrome, with a warning that it’s no longer supported and should be removed. While some users could temporarily re-enable it through Chrome’s extension settings, this is only a short-term fix. Chrome’s updates will continue to disable extensions that don’t comply with Manifest V3.
uBlock Origin Stopped Working
The transition to Manifest V3 has effectively broken uBlock Origin’s core functionality. Even if re-enabled, it can no longer block ads at the same level of effectiveness, particularly on sites like YouTube and social media.
This has led to widespread frustration among users who depended on uBlock Origin for a clean browsing experience.
uBlock Origin Not Supported on Chrome Reddit
Reddit has become a hub for discussions and workarounds. Users on r/chrome and r/uBlockOrigin have shared their experiences, frustrations, and temporary fixes. Some recommend switching to browsers like Firefox, which still support uBlock Origin, while others discuss using “uBlock Origin Lite” or alternative blockers.
uBlock Origin: The End of an Era
With the forced removal and disabling of uBlock Origin, many users see this as the end of an era for ad blocking on Chrome.
The extension, which once boasted tens of millions of users, is now unavailable for download and use on Chrome browsers. This move has reignited debates about user choice, privacy, and Google’s advertising business model.
uBlock Origin Replacement Reddit
With uBlock Origin gone, users are searching for the best replacements. Reddit threads and tech blogs suggest options like uBlock Origin Lite, AdGuard, Ghostery, and Total Adblock. However, none match the full capabilities of the original uBlock Origin on Chrome due to Manifest V3 restrictions.
