In general, "services" are accessed via the xpcom service API. This API
manages keeping track of the single instance of the component.
lxr.mozilla.org is your friend. A quick search for nsICookieService
yields a few good results. The general pattern is:
NS_WITH_SERVICE(nsICookieService, cookieService, kCookieServiceCID, &rv);
eg:
