About this extension
OWASP Top 10 Ref is a lightweight, privacy-first Firefox extension sidebar reference that provides instant access to OWASP Top 10 security risk test cases — all without ever leaving your browser or sending data anywhere.

🔍 WHAT OWASP TOP 10 REF DOES:
• Provides a clean sidebar with all 10 OWASP 2021 risk categories.
• Each category contains detailed subcategories with test methodologies.
• View concrete attack examples and payloads for each vulnerability.
• One-click access to official OWASP Web Security Testing Guide.
• Instant search filtering by category and subcategory names.
• Auto-expand on search to show matching content.

✨ KEY FEATURES:

• Detailed "How to Test" methodologies for each vulnerability.
• Real attack examples and payloads.
• Direct links to OWASP documentation.
• Clean, responsive interface.
• Extremely lightweight (~48 KB).

🔒 SECURITY-FIRST ARCHITECTURE:
• 100% client-side – No external requests.
• No data collection – Explicitly declared in manifest.json.
• No telemetry, no analytics, no servers.
• No eval() or risky innerHTML – Safe DOM methods only.
• Proper input validation on search.
