ketcher running on localhost

[termo...@gmail.com]

with latest firefox I get

TypeError: NetworkError when attempting to fetch resource. index.js:59:1
TypeError: NetworkError when attempting to fetch resource. init-lib.js:56:8

I guess it is CORS related, but I have now tried in many different ways to change the  initIcons(cacheEl) function, but I still don't get the icons showed.

Anybody else with this problem, and how to solve it.
