Over the next few months, MV2 extensions will be gradually turned off by default. Users will be notified in advance and directed to recommended MV3 versions where available.
These changes will start in the Canary, Dev, and Beta channels and gradually broaden to Stable in the following months, with the goal of completing the consumer transition by the end of 2026. Managed devices will not be affected during the consumer rollout. Enterprise deprecation will follow in early 2027.
