Set CSP or Firefox fails to load (301)

Looks like this resource is failing and Firefox shows blank page on https://rntester.now.sh, Windows 10 64bit.

Interesting, that warning/error is actually due to RNTester referencing an http image (only causes an issue on web, not native), and the result should just be that the image doesn't load, not break rendering entirely.

I brought up FF (updated to latest stable version) on my local machine and RNTester renders correctly (even with that warning in the console). Can you do any more digging on your local setup to try and determine why it's a blank screen?

It appears my uBlock pop up blocker was on. Hmmm, maybe serving these assets locally would prevent the popup blocker from interfering?
