Authentication Disabled - We have detected that you are using the v2.x or lower authentication SDKs

[goondu]

1. When launch the site ... it prompted ....

We have detected that you are using the v2.x or lower authentication SDKs with a project that was created at console.firebase.google.com. You must use the 3.0.0 or greater authentication SDKs with projects that have been created in the new console.

From google, it seems like I have to use the version 3 SDK ... thus I set it at index.html

<script src="https://www.gstatic.com/firebasejs/3.0.4/firebase.js"></script>

After making the change , the 'Sign in with Twitter' button no longer responsive.

1. And BTW when using Microsoft EDGE, the 'Sign in with Twitter' button and input box did not show up.
2. And how can I set the default port 8080 to other port number?
