Features: • Set custom HTTP request headers per domain • Add custom cookies per domain • Redirect one domain to another while keeping the original host name — requires the free, open-source header-setter-proxy companion tool, since Google retired Manifest V2 and Manifest V3 blocks extensions from manipulating the Host header directly • Enable or disable individual rules • Exact domain matching without affecting subdomains • Local storage only • No analytics, tracking, remote server, or data collection Open source: • https://github.com/otto-wagner/header-setter Support: • Support development via GitHub Sponsors: https://github.com/sponsors/otto-wagner • Or via PayPal: https://paypal.me/ottowagner
