title: How to open an URL with the default browser with FireMonkey cross-platform applications?
body: <p>Usually, I use: <code>ShellExecute(0, 'OPEN', PChar(edtURL.Text), '', '', SW_SHOWNORMAL);</code></p>
  
  <p>How can I have the same behaviour (opening a link in the default browser), on all platforms (Windows <strong>and</strong> OSX)?</p>
