FreeRefMod Options

Rules

On (untick to send every site its normal referrer)

Checked from the top down: the first rule that fits a request is the one used. Put specific rules above general ones.

See which rule would be used, without visiting anything.

Address being requested From a page on (blank = typed in the address bar) Kind

Appearance Tell me when a new version is out
Once a day, asks thelabs.fyi for the latest version number (nothing about you is sent).

Your rules in a file, to keep or move to another computer. Backups from FreeRefMod 1.x work too.

Target: The site being requested: example.com (and its subdomains), *.example.com, an IP 192.168.1.1, a range 192.168.1.*, with a port 192.168.1.1:8443, or * for every site. A full address like https://router.local/login works too.
Origin: The page the request comes from: a site or IP as above, an IP range ending in .*, same (the same site as the target), other (any other site), or * for anywhere.
Replace: Sends the referrer you type, e.g. a device's own address so it accepts logins from elsewhere.
Remove: Sends no referrer at all, which stops sites seeing where you came from.
Keep: Leaves the referrer alone. Put it above a broad rule to make an exception.
Good to know: This changes the Referer header that reaches the website's server. A page's own JavaScript (document.referrer) is outside what Chrome lets extensions change.
