Cufon make my website disappear in firefox

[4queers]

When I enable cufon my website doesn't load properly in firefox (apart from the background nothing else is displayed).
When I disable it, everything is fine to all browsers.
The problem is that I really want cufon enabled and firefox working.
This is a link to my website: http://www.4queers.gr/
Ι am using joomla 3.1.1, yootheme's subway template and cufon 1.09!
Please I really need some help!
