You're trying to run it as a file from your local computer, right?

Then it's security settings in your web browser preventing cross-site scripting
attacks.

If you use icecat, please install this extension:

  https://addons.mozilla.org/de/firefox/addon/cors-everywhere/

There's an square icon at the top right of the icecat window then (it says 
"cors").

If you click on it it will toggle between green and red.

When it's green it means that it will let all requests pass.  WHEN IT'S GREEN, 
DON'T USE ONLINE BANKING or similar in the same session.

But the index.html frontend application will work just fine then :)

When it's red it means that cross-site scripting attack protection is online.  
If in doubt, leave it red.  It should be red most of the time.

I myself develop like that:

For testing,

* Switch CorsE to green
* Refresh Cuirass frontend index.html page
* Try some stuff
* Close Cuirass frontend index.html page
* Switch CorsE to red
