[Project_owners] Getting Source Tab When Listening to http-on-modify-request

I've thought about using the domain as an identifier but I don't know
if it will help solve my situation. Basically my extension
(cookiestore) has multiple cookie containers (jars) that are sticky to
a tab. The extension intercepts an outgoing requests and adds cookie
headers from the jar. This lets you have separate session cookies for
the same domain each sticky from to a tab. The issue I'm facing is
when a tab that is not the selected one makes an HTTP request in the
background, I need to replace the cookies for the correct jar. To do
this I need to know which tab is making the request so I can use the
correct cookie jar.

Someone suggested the following code on the mozillazine forums, and it
seems to get me close to what I want. I'm able to get information from
the window and document which is for the correct tab, but I'm not sure
how to get the tab object from the window or document so I can use the
tab Id which points to the jar for that tab.

var oHttp = aSubject.QueryInterface(Components.interfaces.nsIHttpChannel);
var interfaceRequestor =
var DOMWindow =
var loadedDoc = DOMWindow.document;

Does anyone know where I can go from here? Is it possible to get the
tab object from the window or document?
