title: Browsersync - How to choose which installation of browser to run?
body: <p>I've just installed <a href="https://www.mozilla.org/en-US/firefox/developer/" rel="nofollow noreferrer">Firefox Dev Edition</a>, and I don't know how to tell <code>browsersync</code> to start with it when I launch it.</p>
  
  <p>I know there is the <code>browser</code> option in which I can specify "firefox", but how can I differenciate one FF installation from one other ?</p>
  
  <p>The issue would be the same if I had various regular FF installed (eg a 3.5, a 48.x and a 50.x).</p>
  
  <p>I can always open manually the right FF and load the page after browsersync started, but I would like it to do it manually (and not to be opened in my regular non-dev FF).</p>
