title: Epiphany browser open URLs in the same tab in python
body: <p>I am using epiphany webbrowser in my Raspberry Pi project. According to the requirement I need to open a link on the same tab using python webbrowser module. But each time a new tab is opened although I've given the parameter new=0</p>
  
  <pre><code>import webbrowser
  import time
  b = webbrowser.get('epiphany')
  b.open('http://www.google.com', new=0)
  time.sleep(5)
  b.open('https://stackoverflow.com', new=0)
  </code></pre>
  
  <p>Any way to resolve this? I need to open urls on the same tab. Any solution from the webbrowser's perspective or python webbrowser module's perspective is highly appreciated.</p>
