Manifest V2 Deprecation: Google Chrome Ends uBlock Origin Support

For years, power users and privacy advocates have fought a renegade rearguard action against Google’s sweeping architectural changes, but the end of the road is finally here. As the final days of June 2026 tick away, the tech giant is preparing to drop the definitive hammer on the web extension ecosystem. The long-debated Manifest V2 deprecation process is reaching its absolute, irreversible conclusion, sealing the fate of the original, full-featured version of uBlock Origin on Google Chrome. With the upcoming release of Chrome 150 on June 30, 2026, Google is closing the very last technical bypass that allowed users and enterprise administrators to keep legacy extensions alive. What was once a slow, staggered phase-out has now turned into a hard, code-level purge. For the roughly 40 million active users of uBlock Origin on Chrome, this transition fundamentally changes how they experience the modern web. It strips away the dynamic real-time filtering that made ad blocking an active defense mechanism, turning it instead into a passive, browser-mediated filter list.
