For the CSS panel we simply use the standard method of
`document.styleSheets` - since Firebug runs with higher ("chrome") JS
privileges, this doesn't run up against same origin restrictions. (The
"Source Edit" feature is more weird; there we use some internal API for
capturing data from requests ("nsIChannel"s), so we are able to present the
original source. It relates to Net panel code, which I don't know a lot
about.)
