title: Opening the external browser out of an RCP application opens Firefox instead of default browser on Linux.
body: <p>When I open an external browser out of my RCP application using:</p>
  
  <p><code>PlatformUI.getWorkbench().getBrowserSupport().getExternalBrowser().openURL(url)</code></p>
  
  <p>It opens up firefox instead of the system default browser (chrome) on Linux (Ubuntu). My default browser is set correctly via update-alternatives and links out of Eclipse actually open in Chrome. The mime type of text/html is also set to chrome. </p>
