Intelligence Summary
Microsoft is discontinuing the Manifest V2 (MV2) extensions platform in Edge. Extensions that still rely on MV2, including uBlock Origin and similar ad blockers, will lose compatibility once the support ends. Microsoft says only a small number of Edge Store extensions with meaningful usage still use MV2. Many affected extensions have MV3 versions, but some may not be available there yet. Users who depend on MV2 ad blockers should switch to MV3-compatible alternatives or a different browser that still supports MV2.
