Referer By Domain gives you fine-grained control over how your browser sends referrer headers. You can: - disable referrers for specific domains, - send only the origin (e.g. https://example.com/), - send the full URL (e.g. https://example.com/path/page.html), or - leave referrers unrestricted. The extension supports: - wildcard rules (*.example.org), - per-domain settings, and - detection and display of related domains (used by background requests). All settings are stored locally in your browser. Nothing is synced or transmitted. 🛡️ Protect your privacy. 🧩 Fix site compatibility when referrers are required.
