Script Shelf

Inventory scripts and stylesheets on the active page with transfer size hints.

Script Shelf lists scripts and stylesheets loaded by the page you are viewing. How it works: • Open a normal http or https page • Click the extension icon and tap Scan assets • See each script/stylesheet with a size hint and URL • Larger assets appear near the top Details: • Includes external and inline scripts when present • Size hints come from Performance resource timings when available • Useful for spotting heavy JS/CSS during performance reviews • Works only on regular websites — not on chrome:// pages • No account and no cloud sync Privacy: • Asset URLs are read only in your browser • Nothing is uploaded to a server • Works offline after install (for already loaded pages)
