Description

CSP Detector helps web developers identify and fix Content Security Policy violations in real-time, right from the browser toolbar. When you visit any page, the extension silently monitors for CSP blocks and instantly shows you what was blocked, which directive triggered it, and how to fix it without ever opening DevTools. Why install it: - Real-time detection — violations appear as they happen, grouped by hostname so you can quickly see which third-party domains are causing issues - Actionable fix hints — each violation includes a plain-English explanation of what to add to your CSP header - Full details on demand — expand any violation to see the blocked URL, page, directive, and policy; copy any value to clipboard with one click - Export your findings — download all violations as JSON or CSV to share with your team or include in a bug report - Zero configuration — just install and browse; no setup, no DevTools panel, no permissions prompts Built for frontend developers, security engineers, and anyone who needs to ship a tight Content Security Policy without the guesswork.
