Angular2 app works in Chrome and IE, but not Firef

App works fine in Chrome and IE(11), but not in Firefox (42.0) or Safari (5.1.7).

FIREFOX:

mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create es6-shim.js:1338:11

Any ideas as to what is wrong greatly appreciated. It looks like it has something to do with "BrowserDomAdapter".

issue resolved by upgrade the es6-shim.
