NoRefTrail lets you choose the sites from which you do not want to send the HTTP Referer header when following external links.
You add the domains you want to the list yourself. When you navigate from one of those sites to a different domain, the extension removes the Referer header before the request is sent.
The extension only affects navigation to external pages. It does not interfere with API requests, XHR, JavaScript, CSS, images, CDN resources, or other background page requests. Internal navigation within the same site is also left untouched.
All settings are stored locally in Firefox. The extension does not collect data, use analytics, or send anything anywhere.
