Microsoft Edge to Drop Support for Older Ad Blocker Extensions by End of 2026
Edge is phasing out Manifest V2—potentially disabling ad blockers like uBlock Origin—moving from Canary/Dev/Beta to Stable and finishing consumer support by end of 2026. Microsoft says 58 MV2 extensions have meaningful usage, and only 3 lack MV3 alternatives; enterprise deprecation starts early 2027.
