Chrome Deletes the Last Manifest V2 Extensions on August 31

Google is deleting Manifest V2 extensions from the Chrome Web Store on August 31, 2026, but this is merely a database cleanup—the extensions actually stopped running over a year ago when Chrome 138 disabled them for regular users in July 2025. If an extension works in your current Chrome browser, it's already Manifest V3, and August 31 won't affect it; the alarming install counts on dead listings represent outdated machines and enterprise systems still running older Chrome versions.
