title: How to kill the browser instance (chrome) that was opened by web driver previously
body: <p>I want to kill the browser instance (chrome) that was opened by web driver previously. How would I do that? In my code below, I intentionally didn't want to include quit() or close() as I want to leave the browser open. So every time I execute or run this program, I want to kill/close the previously opened browser and then start a new instance and leave it on. As a result, only one instance of browser should be open at a time. I am using Mac. </p>
  
  <pre><code>public static void main(String[] args){
  
      String website = "http://www.google.com";
      System.setProperty(".....");
      WebDriver driver = new ChromeDriver();
      driver.get(website);
  
  }
  </code></pre>
  
  <p>The behaviour atm is that everytime I execute this, chrome instance will just pile up. What is the best way to avoid this? I am not doing this for testing purpose. I'm doing this because I want to automate a task. Thanks. </p>
