Well this explains it. I was getting an HTTP 502 on appleid.apple.com while trying to add Apple Pay support to a product I am working on. I called apple support to tell them the site was down. The support agent told me, and I quote, "Our internet is Safari. We don't support Firefox." I guess Apple doesn't want developers to support their products.
