Firefox 23 & Google Chrome Issues

Prezi Team,

I help run a site InFocus.emc.com. We admin it through wordpress. We've been finding that on Firefox version 23 the prezi will not play, there is content being blocked. We've tried fixing the URL, changing security settings, and still we cannot view the prezi. Is prezi not made to run on firefox 23?

Another issue we recently got was an error on Chrome: Technical details:
id: 1100 the reason is: Event [Event type="fontLoadError" bubbles=false cancelable=false eventPhase=2]

Any input would be greatly appreciated!
