How to add Content Security Policy to firefox extension when using addon sdk?

Question

I am using firefox add-on sdk to convert my chrome extension to a firefox addon. But I am getting Content Security Policy: The page's settings blocked the loading of a resource at data:text/html;charset=utf-8 error. I am injecting a local html in an iframe following this link. Any idea how to achieve this? For chrome extension I followed this link.

I found a solution that works for me.

I add to my package.json the following line:

"permissions": {
    "cross-domain-content": ["https://www.foo.com/"]
},

Where https://www.foo.com you can add the domain or the list of domains that you are accessing.

For more info go to the Cross Domain Content Scripts
