Add a Custom Request Header in Chrome

Tip: Use share links to sync the header across your team.

TL;DR: Install the MV3 header editor, add a per‑site rule with your header name/value, then verify in DevTools. Share via /s#c=... to keep configs client‑side.

  1. Install the Chrome header editor.
  2. Create a rule with your header name and value, scoped to your domain.
  3. Verify in DevTools → Network that the header is added.
