Google I/O 2026 brought several notable updates for Chrome extension developers. Monthly developer registrations have more than doubled over the past year, with 17% of new extensions using AI. Key announcements include: a Modern Web Guidance skill for AI coding agents tailored to extension development; Chrome DevTools for agents now supporting extension debugging (install/uninstall, reload, inspect popups and service workers); granular member roles (Admin, Item Manager, Viewer) in the Chrome Web Store Developer Dashboard; a new private enterprise publishing option allowing extensions to be deployed to external organizations; and Chrome's adoption of the standard browser global namespace for improved cross-browser compatibility.
