About ModHeaders

ModHeaders lets you set, append, or remove HTTP request and response headers for any site you choose, with rules matched by URL, domain, or regex and filtered by resource type. Manage everything from a clean side panel with a master pause toggle, search, duplicate, and JSON import/export. Built on Manifest V3 declarativeNetRequest, all rules stay local in your browser - no accounts, no data collection, no network activity.
