Users online are reporting on Reddit and X that Chrome is removing outdated extensions. In Chrome, a notification window will appear underneath the extensions tab on the browser taskbar with a message encouraging users to remove the impacted add-on, saying it has been turned off and is “no longer supported.” Two buttons are available that allow users to either quickly delete or manage their extensions.

These changes come as Google migrates Chrome away from the now defunct Manifest V2 specification. Support is being killed not just for uBlock Origin, but for any extension that hasn’t (or is unable to) update to Manifest V3. uBlock Origin users can switch to uBlock Origin Lite, which has more limited filtering capabilities than its predecessor due to Manifest V3’s ad blocking restrictions.
