Switch grouped request headers without leaving your tab. Headerleaf keeps request headers in named profiles. Select a profile, enable the rows you need, and its headers are applied to new browser requests immediately. - Create and rename multiple profiles - Switch the active profile with one click - Add, edit, enable, disable, and delete header rows - Apply headers to fetch, XHR, navigation, scripts, images, WebSockets, and other request types - Store configuration locally in `chrome.storage.local` - Modify requests through the native Manifest V3 `declarativeNetRequest` API Only the selected profile is active. Repeated header keys are de-duplicated, with the last enabled value winning.
