title: Many Firebase-Elements slow everything down
body: <p>In true Polymer fashion I'm building all of my elements as stand alone components that could be reused on their own. My app uses a Firebase database and the firebase-element elements to show data, and does a marvellous job at this, but the elementisation of my app means that it creates a gazillion Firebase instances I think. Should I put one on the window and share that between all of them, or is there a more gracious solution.</p>
  
  <p>Thanks a million!</p>
