## Description

<strong>Retire.JS Pro</strong> scans every script loaded by the pages you browse and alerts you when a known-vulnerable JavaScript library is detected.

<strong>How it works:</strong>
- Intercepts all script requests in real time
- Detects by: URL pattern, filename, file content, SHA1 hash, and function-based version extraction
- Shows full vulnerability details: severity, CVE/GHSA identifiers, and reference links
- Exports a self-contained HTML report (dark or light theme)

<strong>Features:</strong>
- Dark mode by default, with persistent light/dark toggle
- Scanned page URL shown in popup and included in every report
- Zero data collection — all scanning is local, nothing leaves your browser
- Powered by the <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/d4f8aad790e27043ce2955198303b489eb85db30fe03118674bb1486d50da74e/https%3A//github.com/RetireJS/retire.js" rel="nofollow">RetireJS</a> vulnerability database (65 libraries, 488 vulnerability records, 346 CVEs)
