title: Lauch external program in firefox or chrome
body: <p>We have a custom web app in our intranet that allow users to browse and search our shared file system in a way more appropriate for our organization. as compared to windows explorer/mac finder. However, when the users click on, for example, a link pointing to a word document the document is downloaded by the browser and then opened. I am trying to provide a better way, namely that the file is opened directly from the shared folder that each user has mapped in his own computer. This will make things faster and will not pollute the browser download folder.</p>
  
  <p>I was planning to create a chrome or firefox extension that recognizes certain css class attached to a link, remaps the link to the shared file system and and launch an external process. Any idea how to achieve this? Is there a better solution?</p>
