		ua := args[3].(rnt.Str).Value()

		inCookies, err := netlib.GetCookieString(jar, urls)
		if err != nil {
			panic(rnt.RaiseType(lib.ExtractorErrorType, err.Error()))
		}

		html, outCookies, err := browser.Load(urls, ua, inCookies)
		if err != nil {
			panic(rnt.RaiseType(lib.ExtractorErrorType, err.Error()))

		if err != nil {
