"[Report Only] Refused to load the font... because it violates the following Content Security Policy directive: "font-src 'self' *"."
It's coming up in relation to both modernizr and the index.
I am currently using web fonts from "Cloud Typography", the errors seem to be relatively new and were not present when I first applied the service to the Shopify website.
The error is set to report only so it won't impact other scripts on the site. This is not something you'll be able to change / adjust yourself, but there is some info on the Adobe Typekit help pages should you be curious.
All the sites I've seen so far with typekit in place load the font correctly across browsers and platforms. It would bother me seeing the report in the console too, so I feel the inner developer annoyance on that one ;)
@Andrew: Yes, it should be across the platform since everyone will share the same CSP policy.
@Matthew: Now if it's failing completely I would think you've got issues with the implemetation and not what others are seeing here. I checked your site and don't see typekit being used at all. Perhaps you've removed it since your post.
