Google is removing the original uBlock Origin ad blocker for more users as it transitions to a new extension system called Manifest V3. This change affects not only uBlock Origin but also other extensions that have not updated to the new standard.

Why is Google Removing uBlock Origin?

Google says that Manifest V3 is designed to improve privacy and security. However, it also removes certain features that many ad blockers rely on to function properly. Because of this, uBlock Origin and other older extensions are being disabled.

How Are Users Affected?

  • Many users on Reddit and X (formerly Twitter) are reporting that Chrome is turning off old extensions.
  • A notification in Chrome tells users that their extension has been disabled and offers options to remove or manage it.
  • Google began phasing out uBlock Origin in October 2024, but more users are now noticing the impact.

What Can Users Do?

  • Switch to uBlock Origin Lite – This version is still available but has fewer ad-blocking features due to Manifest V3 restrictions.
  • Use an alternative browserFirefox still supports the older extension system, making it a good choice for uBlock Origin users.
  • Check for updates – Some extensions may release new versions that work with Manifest V3.

Other Browsers Affected

  • Microsoft Edge (which is based on Chromium) is also losing support for old extensions.
  • Brave browser will offer limited support for Manifest V2 extensions.
  • Mozilla Firefox will continue supporting both V2 and V3 extensions, making it a possible alternative for users who want to keep using uBlock Origin.

As Google moves forward with Manifest V3, users who rely on ad blockers may need to adjust their browsing experience or switch to browsers that still support the older system.
