Steps to reproduce

1. Prepare fresh Firefox Profile
2. extract MyEtherWallet-v6.6.7.zip
3. Open MyEtherWallet-v6.6.7/index.html in Firefox
4. look at the BLANK PAGE

What do you expect to happen?

To be able to use the Online local zip file version.

What happens instead?

MyEtherWallet-v6.6.7/index.html is a blank page

With firefox dev tools error:
MyEtherWallet-v6.6.7/app~d0ae3f07.8898fc8fec836690d960.js” is not eligible for integrity checks since it’s neither CORS-enabled nor same-origin.

This even happens on the previous v6.6.6, why has no one seen this issue? Is it even tested on Firefox before release?
I have tried on multiple fresh Firefox profiles.

@re42 for the online local version, you have to serve the. online local version.

I'm having the same issue with the normal version. The offline version works but is very slow. I don't understand what is "serve the .online local version". Can someone explain what I'm supposed to do?

Also on Ubuntu and Firefox, also seeing blank page.
