Answer 1

Firebaser here

The new Firebase Authentication currently doesn't work in React Native due to a dependency on the window object. We're looking if that's something we can improve, but no guarantees.

From Jacob's post on the firebase-talk list:

As a "workaround" if you don't need auth (unlikely, I know, but still worth mentioning), you should be able to do the following:

var app = require('firebase/app');
var database = require('firebase/database');

Answer 2

Apparently, the new Firebase Javascript client library depends on localStorage, and thus fails to start in some cases, such as Safari in Private Browsing Mode.

As a workaround, I uploaded a patched version of the new client library to github: https://github.com/urish/firebase-localstorage-fix/blob/master/firebase.js

I do hope that the team will fix this issue soon, but in the meantime the patched version does the trick for me.
