More About Auto Referer

Control HTTP Referer to protect privacy and not break web. Open source at

Referer policy:

1. For webs' top frame (i.e. clicking link, navigating, redirecting etc.):
1). If origin and target url have same domain, allow trimmed referer
2). If origin and target url have different domain, no referer

2. For in-page resources (images, videos, js, css etc.), allow trimmed referer (this is **the key to not break** most webs, also a balance between privacy and experience)

3. Trim referer: Any referer should be no more than `http(s)://domain-name:port/`

4. Not allow referer that not starts with "http" or "https". (Please feedback if you find something broken due to this)

5. No referer when downgrade from HTTPS/WSS to HTTP/WS

We believe that can protect privacy enough and won't break web.

If user find a web broken, user can temporary set this addon disabled via toolbar button for:

- this one tab
- this one tab and new tabs opened by this tab
- this one window (Firefox only)
- globally

(above can be set as keyboard shortcuts)

there's showy toolbar button badge indicating disabling status.

## Notice
Due to browser bug on javascript `document.referrer` , using a regular referer controlling addon you can get 70% of expected protection until they fix that bug.

So, we've implemented a workaround to improve protection to 85%. Please enable workaround in addon settings .

This addon doesn't use content script. Content script hiding `document.referrer` is not 100% reliable.

Instead, we use this workaround to kill `document.referrer`:
Cancel all cross-domain navigating requests and make freshnew ones, like directly hit (currently only implemented for GET method and main frame, other methods and sub-frames remain as is)

## Allowlist

Currently it has hard-coded allowlist.

## Disclaimer

This open souce addon comes with no warranty. Use on you own risk!
