About HeaderTweaker

HeaderTweaker lets developers, testers and/or power‑users inject, modify, or remove headers to outgoing HTTP requests on the fly. Whether you need to test APIs that require special authentication tokens, run A/B tests, simulate different browsers or debug CORS issues, this lightweight extension gives you full control over the outgoing headers without touching server code.
