How To Know Loaded Window Is Firefox Electrolysis Window

I want to code a functionality for Firefox Electrolysis window. But how can I know loaded window is Firefox Electrolysis window but not the normal Firefox window? var WindowListene

Solution 1:

Components.utils.import("resource://gre/modules/Services.jsm");

var myObserver = function(subject, topic, data){
  if(subject.gMultiProcessBrowser){
    //electrolysis
  }
  else{
    //oxidation
  }
};

Services.obs.addObserver(myObserver, "browser-delayed-startup-finished", false);

//Since your restartless addon can be disabled, removed or updated
//remember to remove it during cleanup
Services.obs.removeObserver(myObserver, "browser-delayed-startup-finished", false)
