I personally use the headless driver PhantomJS. This works fine for me, but I didn't tried with FirefoxDriver. You haven't shown what you tried so far, so I don't know which driver you use and if you already tried this.

WebDriver driver = new PhantomJSDriver();
driver.manage().window().maximize();
File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

Now you can save the screenshot file with simple IO. Maybe this is helpful, too.
