Modify the Referer header of HTTP requests: Remove, shorten, replace with custom data, or keep the Referer depending on the target domain.
What is Referer Modifier?
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
document.referrer is modified to match.
