javascript - How to set Content Security Policy in Chrome Extension Manifest.json in order for Firebase to work

Question

I made a Chrome Extension and used Firebase to collect data into a database. It worked fine for some time, but it seems there were some changes to Chrome. Now I get the following error in the javascript console when using Inspect Element on my Extension:

Refused to load the script 'https://(myID).firebaseio.com/(otherprivatedata)' because it violates the following Content Security Policy directive: "script-src 'self' chrome-extension-resource:".

This script is written at firebase.js:171, it's not script that I added.

I attempted to follow this guide and add the "content_security_policy" tag to my manifest.json as instructed: https://github.com/firebase/firebase-chrome-extension

I added the following line to my manifest.json as instructed:

"content_security_policy": "script-src 'self' https://cdn.firebase.com https://*.firebaseio.com; object-src 'self'"

However when I add this line, I now get an error when trying to load my script in chrome://extensions

Error Loading Extension

Failed to load extension from: ~XXXmy_ext

Manifest is not valid JSON. Line: 14, column: 5, Syntax error.

And it highlights the line I just added above (content_security_policy). What am I doing wrong? It seems anything after "content_security_policy" is completely refused by Chrome.

Even when I try the sample code from Google, it doesn't work. developer.chrome.com/extensions/contentSecurityPolicy

"content_security_policy": "script-src 'self' https://example.com; object-src 'self'"

How can I set the content_security_policy in order for Firebase to work in an Extension?

(My firebase.jp is already downloaded and packaged in with my Extension since Chrome won't let me call it as remote.)
