GeckoWebExecutor is responsible for fetching a WebRequest and delivering a WebResponse to the caller via fetch(WebRequest). Example:

     final GeckoWebExecutor executor = new GeckoWebExecutor();

     final GeckoResult<WebResponse> result = executor.fetch(
             new WebRequest.Builder("https://example.org/json")
             .header("Accept", "application/json")
