Customize Firebase hosting preferences

[ghost]

I added some external links in my webapp mcschool.ca but I am not able to open them. I got below error: No 'Access-Control-Allow-Origin' header is present on the requested resource.

My research shows Firebase allows you to add header to solve this issue: "hosting": { // Add the "headers" section within "hosting". "headers": [ { "source" : "**/.@(eot|otf|ttf|ttc|woff|font.css)", "headers" : [ { "key" : "Access-Control-Allow-Origin", "value" : "" } ]

I can't find out where to add this setting within app-framework. Can you please advise?

@yuantw - Can you please provide an example for what you get this error? The source and place you load the external content? Thanks!
