title: Google Chrome extension run as if in console?
body: <p>I'm trying to make a Google Chrome extension that pauses/plays the payer in DEEZER (www.deezer.com). I i manually run the code "<code>playercontrol.doAction('next')</code>" in the Google chrome JavaScript console, I can manipulate the deezer player, so i looked at the possibility of injecting the code into the Deezer web page with an extension but I haven't managed to do so successfully.
  Is it possible to run JavaScript code in Deezer web page as if it were coming from the console in Google Chrome?
  If so how?</p>
