I just tried with Chrome 34.0.1847.131 on a Mac. I was able to register and my account was created automatically as expected. Can you let me know more about what isn't working:
* Are you getting a blank page?
* Is the FB Login popup showing at all?
* If it shows, after you enter your credentials, does it not redirect?
Any more information you can provide as to where things seem to break down would greatly help. From what I see, things seem right, but we'll gladly help investigate anything you are having issues with.
Thanks,
Alex
