Header Override од headeroverride.com

Header Override is a developer tool for managing URL-scoped rules that modify request headers, response headers, request Cookie values, and response Set-Cookie values.

Create rules from the extension popup, choose whether each rule affects outgoing requests or incoming responses, and scope each rule with browser's declarative URL filter syntax. Header Override can add request headers, add response headers, append request Cookie values, and add response Set-Cookie values with common cookie attributes such as Domain, Path, SameSite, lifetime, and Secure.

Use profiles to keep separate rule sets for development, QA, demos, clients, or debugging sessions. Profiles can be activated from the popup, and selected profiles can be exported or imported as JSON when you need to move configurations between browsers or machines.

Rules are saved locally in browser and applied automatically with browser's declarativeNetRequest API. Header Override does not use analytics, tracking, remote code, or external servers.
