Gimme Sum Headers!

Applies local header sets to selected HTTPS sites; it is not a password manager.

Gimme Sum Headers! applies reusable request-header sets only to the HTTPS sites you choose. Create a header set once, then map it to one or more exact hostnames or wildcard defaults. Exact host mappings override wildcard defaults, so you stay in control of which credentials are sent where. Built-in presets support Cloudflare Access service tokens and Bearer tokens. You can also create constrained custom header sets for your own services. Features: - Reusable header sets for Cloudflare Access, Bearer tokens, and custom headers - Map a set from the toolbar popup while visiting an HTTPS site - Exact hosts override wildcard defaults - Optional host access is requested only for the sites you explicitly configure - No accounts, telemetry, analytics, cloud sync, remote code, or developer-operated service Security note: header values remain in your local browser profile so they keep working after restart. This extension is not a password manager or hardware-backed secret vault. Use dedicated least-privilege credentials, prefer exact host mappings, and revoke credentials if your browser profile is compromised. Header values are sent only with requests that match your enabled HTTPS site assignments.
