Can you guys kindly point me to an object/api by which i can extract/access referrer information of a page. Things like: 1) Referrer Url (I am already able to extract it) 2) path to current page (i.e. by clicking a link/ form submit in referrer page or through address bar) 3) whether user arrived at this page by clicking backward/forward button For google chrome, I understand that the above information can be extracted through transition qualifiers (http://developer.chrome.com/extensions/webNavigation.html). I would be most grateful if i am pointed to the right url / source within mozilla docs (not able to find it :().
