CST Verdict

Based on our analysis of core features, here is our conclusion:

HTTP Header Live

Penetration testers and web application security researchers who need quick visibility into request and response headers during manual testing should use HTTP Header Live; it's free, integrates directly into Firefox's developer workflow, and eliminates the friction of switching between browser tools and command-line utilities. The extension lets you inspect and modify headers in real time without touching Burp Suite, which matters when you're doing rapid reconnaissance or validating specific header-based vulnerabilities. Skip this if you're looking for automated header scanning, compliance checking, or anything beyond the browser; it's a practitioner's scratchpad, not a security platform.
