About this extension
Script Sentinel helps developers generate Content Security Policy recommendations directly from the current Firefox tab.

When you click Generate CSP, the add-on sends the active tab URL to the Script Sentinel scanner, analyzes the resources the page loads, and returns a readable CSP recommendation. It can scan 1-3 pages, detect scripts, styles, images, fonts, frames, connections, mixed content, external domains, and optional SHA256 hashes.

The add-on includes local recent scan history, a clear-history control, copyable CSP output, optional security header pack output, and a link to the full scanner at https://script-sentinel.com/generate-csp.

The Firefox add-on is a free companion to the Script Sentinel website. Premium services are available separately at https://script-sentinel.com/pricing and include authenticated website scans up to 10 pages, CSP drift monitoring, scheduled scans, dashboard history, site verification, email alerts, rollout guidance, and developer export tools. Those premium features are not included inside the add-on.

Privacy-first behavior: the add-on does not scan in the background, does not collect browsing history, and only sends the active tab URL when you explicitly click Generate CSP.
