If you use uBlock Origin on Microsoft Edge, it's time to start looking at alternatives. Microsoft has shared a timeline for the transition away from Manifest Version 2 (MV2) extensions. That transition will end support for uBlock Origin on Edge, alongside a small group of other extensions.
Microsoft aims to fully transition consumers away from MV2 extensions by the end of 2026. Some users will start seeing notices about the change this month (August 2026). Microsoft will then gradually turn off MV2 extensions by default over the coming months.
