Microsoft Edge is ending support for the Manifest V2 (MV2) extensions platform, a move that will disable popular ad blockers including uBlock Origin — mirroring a similar change Google Chrome made earlier in 2026.
The transition will begin in Edge’s Canary, Dev, and Beta channels before rolling out to the Stable release over the following months. Microsoft has set a target of completing the consumer transition by the end of 2026. MV2 extensions will be gradually turned off by default, with users notified in advance and pointed toward recommended Manifest V3 (MV3) versions where available.
According to Microsoft, only 58 extensions on the Edge Add-On Store have “any meaningful usage” and still rely on MV2, with just three of those lacking an MV3 alternative.
Enterprise and managed device users will face a separate, later timeline. Managed devices will not be affected during the consumer rollout, with enterprise deprecation scheduled to follow in early 2027.
For everyday Edge users who rely on MV2-based ad blockers, this change may result in those extensions being disabled without a direct replacement unless a compatible MV3 version exists. Users of affected extensions should watch for in-browser notifications from Microsoft directing them to updated alternatives.
