Addons & Local 5.x Content Security Policy

Refused to connect to 'https://XXXXXX' because it violates the following Content Security Policy directive: "connect-src 'self' https://* http://localhost:* ws://localhost:* https://localhost:* https://* https://* https://* https://*".

This change seems to be undocumented (since 5.x).
How can we deal with that when our local addon needs to get information for another service?

@flyjack , taking a chance here?

@clay ? Any help with the AddOns and changes made?
