## Description

Email Header Analyzer is a security-focused Firefox sidebar that turns raw email headers into actionable intelligence - instantly and privately.

Paste any email header and immediately see:
• The real originating IP (with private ranges filtered).
• Every IP address with one-click links to AbuseIPDB, VirusTotal, and IPinfo.
• All email addresses with checks on Have I Been Pwned and <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/12af1f305d2c849786eed0b7c039203b2d4815968c6fce58d81ee278a67986d3/http%3A//EmailRep.io" rel="nofollow">EmailRep.io</a>.
• Full Received chain in correct chronological order.
• SPF, DKIM, and DMARC authentication results.
• Clean buttons to copy the original header or full analysis report.

Designed for security analysts, phishing investigators, and abuse teams who need speed without sacrificing privacy.

• No network requests, no telemetry, no data collection.
• No unnecessary permissions.
• Built with secure DOM practices (no innerHTML, no eval).
