I’m experiencing same issue with just a black box appearing on Firefox. Works beautifully on IE, Chrome, Safari on iPad and my Droid Bionic, but just a black rectangle where video should be on Firefox. Using Genesis Minimum theme. Interested in hearing of any fixes.

Sorry folks – newbie mistake – found confirmation emails from MailChimp waiting in the inboxes of my test email accounts. Once I confirmed in email, users added as expected.
