title: How to open url to the same tab if its already open in browser
body: <p>I am facing some challenge-
  Lets consider I have a menu and under that I have 3 links-</p>
  
  <pre><code>About
  Contact Us
  FAQs
  </code></pre>
  
  <p>By default home page is About menu item.
  Now when I am clicking on "<strong>Contact Us</strong>" , I want to open a new tab on same browser window. And without closing this if again I am clinking on "<strong>Contact Us</strong>" from the first tab, <code>this time I do not want to open new tab because I have already an open tab for Contact us</code>, I just wanted to navigate to the same one which is earlier opened.
