Stop link from sending referrer to destination

I was looking for just the same thing, and it seems like this will be a feature of HTML5.

The tag you are looking for is rel="noreferrer".

It is already implemented in Webkit (Chrome, etc.), as well as Firefox, but your mileage may vary.

As of 2020, it is supported in all major browsers, with the exception of Opera Mini and old versions of IE11.

For anyone who's visiting in 2015 and beyond, there's now a proper solution gaining support.

The HTTP Referrer Policy spec lets you control referrer-sending for links and subresources (images, scripts, stylesheets, etc.) and, at the moment, it's supported on Firefox, Chrome, Opera, and Desktop Safari 11.1.

Edge, IE11, iOS Safari, and desktop versions of Safari prior to 11.1 support an older version of the spec with never, always, origin, and default as the options.

According to the spec, these can be supported by specifying multiple policy values. Unrecognized ones will be ignored and the last recognized one will win.

<meta name="referrer" content="never"><meta name="referrer" content="no-referrer">

Also, if you want to apply it to audio, img, link, script, or video tags which require a crossorigin attribute, prefer crossorigin="anonymous" where possible, so that only the absolute minimum (the Origin header) will be shared.

(You can't get rid of the Origin header while using CORS because the remote sites need to know what domain is making the request in order to allow or deny it.)

HTML 5 includes rel="noreferrer", which is supported in all major browsers. So for these browsers, you can simply write:

<a href="example.com" rel="noreferrer">link</a>

There's also a shim available for other browsers: https://github.com/knu/noreferrer
