Warning: unreachable code after return statement (Line 460:bower_components\app-storage\app-storage-behavior.html)

OS: Windows 10 Pro
Browser: Firefox 48.0b1
My app Url: https://note-app-e3dfc.firebaseapp.com/

So, I'm going through the following demo, which coincidentally happens to be the same as the Demo in polymerfire:

Build a Progressive Web App with Firebase, Polymerfire and Polymer Components

The first issue I'm having, which does not happen on my android device, is how slow the initial load is. Initial load can take up to 14 seconds, when viewed on chrome, Firefox, and edge on Windows Pro 10. Looking at console readout of Firefox reveals the above titled warning message, which appears first in the actual readout. So I'm presuming that this may have something to do with the slow load time

The second issue I'm having, which does not happen on my android device, is that upon typing a note, the text is being written backwards, as in the cursor is on the leftmost of the entry box, but typing a word like 'testing', appears as 'gnitset'. Words are being written right to left!

Running my demo app on windows, as specified above, will reveal all that I mention.

What is the issue here?

Ok, on further investigation, it appears that the app works correctly in Chrome ver: 51.0.2704.106 m (64-bit).

So the anomalies I was experiencing are Firefox specific.

Thanks for the report -- it looks like the actual error is coming from PolymerElements/app-storage -- would you mind filing a bug there as well? I'll leave this open until it's fixed.

@TheoMer is this fixed?
