Translated into the language of your choice:
nsCOMPtr<nsIDOMDocumentView> docView = do_QueryInterface(document);
nsCOMPtr<nsIDOMAbstractView> defaultView;
docView->GetDefaultView(getter_AddRefs(defaultView));
nsCOMPtr<nsIDOMViewCSS> cssView = do_QueryInterface(defaultView);
nsCOMPtr<nsIDOMCSSStyleDeclaration> cssDecl;
cssView->GetComputedStyle(element, "", getter_AddRefs(cssDecl));
nsString fontFamily;
cssDecl->GetPropertyValue("font-family", fontFamily);
where document is an nsIDOMDocument and element is an nsIDOMElement.
(uncompiled/tested; it's at least close to correct, though.)
Of course, this won't actually tell you what font ends up being used.
Font selection is buried deep in the graphics code, and isn't exposed
anywhere.
