Answer 1

i have the issue with firebase.util lib, as Rodrigo said i think is problem of the versión.

Before:

    var ref = new Firebase('url');

Now:

    firebase.initializeApp(config);

As the firebase object is defined differently it does not find it. In my case, I need to update the library to be compatible with version 3.0 of firebase. I do not think it's a good idea to use the old library, to get out of step is fine but will have to update the codes to version 3. If no one has done yet may be our opportunity to contribute to the community.
