Referer Modifier

Modify the Referer header of HTTP requests: Remove, shorten, replace with custom data, or keep the Referer depending on the target domain.

Referer Modifier: Customize HTTP Referer Headers

Referer Modifier is an efficient Firefox add-on meant for managing the HTTP Referer header. This add-on allows users to set up rules for each target domain, deciding whether to keep, prune, remove or replace the Referer. Users can also designate default actions for domain-based requests and those that don't match any existing rule. It offers easy JSON configuration import/export, and since version 0.8, allows for modification of the Javascript property document.referrer to align with changes.

Add-on summary

Analyze keywords

Referer Modifier lets you configure rules to decide what HTTP Referer header Firefox should send to a certain site, if any. For each target domain, one of five actions can be configured:

  • Keep: Do not modify the Referer
  • Prune: Send only the origin part of the Referer (scheme, host, and port)
  • Target: Send the origin of the target URL (scheme, host, and port) as Referer
  • Remove: Send no Referer at all
  • Replace: Replace the Referer with a configured value
You can configure default actions for requests originating from the same domain, and any other request not matching a domain rule. The "replace" and "target" actions will create a Referer header if necessary, the others only modify or remove existing ones. The configuration can be exported as and imported from JSON files.

Since version 0.8 the Javascript property document.referrer is modified to match.
