FreeRefMod

FreeRefMod Chrome extension lets you customize the HTTP Referer header on a per-site basis. Build safe allow/deny rules so sites get only the referrer you intend — or none at all. We use this to log in to certain devices that won't allow off network logins. Or use it to help prevent REFERER tracking.

Features

  • Create per-site rules using origin and target matching.
  • Built on Chrome's declarativeNetRequest rules for speed and privacy.
  • Quick toggle from the options page to enable/disable rule sets.
  • Import/export rules as JSON for backup or sharing.
  • Safe defaults that respect Chrome's referrer policy.

FAQ

How do I update to a new version?
Remove the previous folder, download the new ZIP, and use Load unpacked again. Your extension data remains unless you remove it from Chrome.
Where are settings stored?
Both extensions use Chrome storage APIs. You can export/import rules from the options page.
