OpenHeader — HTTP Header Editor Edge extension security report

OpenHeader changes your HTTP header rules — and never reads or intercepts your traffic. It applies changes through the browser's official declarativeNetRequest engine, which means the extension only declares header rules to the browser. It cannot see, log, or transmit your requests, by design. WHY THIS EXISTS Built as a clean, safe alternative to ModHeader — no ads, no tracking, no account, and small enough to read the whole source in one sitting. FEATURES • Add, modify, and remove request headers • Add, modify, and remove response headers • Multiple profiles — switch header sets in one click • Per-profile URL filters — apply headers only to the sites you choose • Import / export your settings • Master on/off toggle with an active badge PRIVACY • No analytics, no trackers, no advertising SDKs • Your header rules are stored locally in your browser and are never sent anywhere • Minimal permissions • Open source (MIT): https://github.com/smartfabai-commits/openheader
