Chrome Extension Watchdog

Chrome Extension Watchdog helps you understand what your installed extensions can do, and how they may be changing pages. Extension inventory: • Lists all installed extensions with version, status, and permissions • Each permission shows a plain‑language explanation on hover • Permissions are color‑coded (low / medium / high risk) Page change detection: • Watches for risky changes like new scripts, iframes, form actions, URL/source changes, inline handlers, and sensitive inputs • Shows “high‑signal” changes that matter for security • Tries to attribute changes to the extension that likely caused them Alerts and storage: • Alerts are saved in local browser storage (browser.storage.local) • No data is sent to any server • You can filter by site/date and export alerts as JSON How to use: • Browse normally, then open the popup for a summary • Click “Open details” to review full evidence and attribution in the dashboard
