title: Selenium WebDriver - check if window is full screen
body: <p>I'm working in Groovy\Java with Selenium WebDriver. Is there a way to check if the browser window is full screen (for example if someone pressed F11)? I have tried to search for other questions on StackOverflow but I have only found ways to set fullscreen, not to check if the window is already full screen.</p>
  
  <p>Any ideas?</p>
