NoRefer 2 per CC First

Per-domain HTTP header editor. Set, append, or strip any request or response header, scoped to the sites you choose.

NoRefer 2 lets you rewrite HTTP headers on the sites you choose — the modern successor to the original NoRefer extension, rebuilt on Manifest V3.

WHAT YOU CAN DO
• Set, remove, or append any header
• Edit both request headers (sent by your browser) and response headers (sent back by the server) • Scope each rule to specific domains — subdomains included automatically — or apply it everywhere
• Match by the target host, by the page the request comes from, or by a URL filter like ||example.com/api/*
• Order rules to control which one wins when two touch the same header
• See a per-tab badge counting the rules active on the current site, and flip everything off with one master switch

COMMON USES
• Strip the Referer header for privacy
• Send Do-Not-Track / Global Privacy Control signals
• Spoof a User-Agent on a specific site
• Drop Content-Security-Policy or set Access-Control-Allow-Origin while developing locally
• Add an Authorization or custom header to an internal API you're testing

FAST AND PRIVATE Headers are rewritten by the browser's own declarativeNetRequest engine, so edits apply natively without any extension code sitting on your traffic. Everything is stored locally on your device. No accounts, no telemetry, no servers, no data collection.

Presets get you started in one click, and you can import/export your rules as JSON — including an importer for configs from the original NoRefer.
