I love how everyone is hating on FireFox because you're all used to GC, but FireFox was probably the browser you all used before Chrome was even announced.
Oh, and for those of you using Safari, please proceed to unplug your computers and toss them in your trash cans.
Site's working 100% fine for me, FireFox isn't broken like Chrome.
Oh, and it's probably a CloudFlare problem either way.
