My Shopify App Not Work on Firefox - Blocked by Content Security Policy

[YoussefAfla]

Hello,

I have a problem with my Shopify app

my app works great on Chrome but no work on Firefox

When I enter to it from firefox I have this error message

Blocked by Content Security Policy

An error occurred during a connection to nimopping.myshopify.com.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it.

My app developed by NodeJS and Express

I really need your help guys

Thank you
