According to Wikipedia, HTTP Referrer — also known by the common misspelling referer that occurs as a HTTP header — identifies, from the point of view of an internet webpage or resource, the address of the webpage (commonly the URL, the more generic URI or the i18n updated IRI) of the resource which links to it. By checking the referrer, the new page can see where the request came from.

Referrer logging is used to allow websites and web servers to identify where people are visiting them from, for promotional or security purposes. Referrer is a popular tool to combat cross-site request forgery, but such security mechanisms do not work when the referrer is disabled. Referrer is widely used for statistical purposes.

Many web sites log referrers as part of their attempt to track their users. Most web log analysis software can process this information. As referrer information can violate privacy, some browsers allow the user to disable the sending of referrer information. If you want to stop Firefox Browser from sending the referrer, here is how to do it :

  1. In the address bar of your Firefox browser type: about:config and hit Enter.
  2. In the Filter input field type: network.http.sendRefererHeader.
  3. Double click on the preference name.
  4. Change the value from 2 to 0 and hit OK.

The downside of  http referrer if disabled on your browser is you can not logon to the site that using content based on referrer.
