Chrome's Shift to Manifest V3 Narrows Ad Blocker Capabilities

Chrome is phasing out Manifest V2 extensions, the architecture powering ad blockers and privacy tools for tens of millions. Manifest V3 replaces dynamic request-blocking with static rules and enforced limits, materially constraining what third-party extensions can filter. Some developers have adapted, though creators like uBlock Origin argue the new model reduces blocking effectiveness. Migration to stable Chrome is imminent.
