Site Breaking up Firefox 3.6

[cshart]

Zen Cart 1.3.8a nothing added just the design.

Works fine in IE, Safari and Opera but Firefox 3.6 breaks up coding. Is there something I can do to prevent this?

Anyone see a solution to this problem?

Thanks,

Looks exactly the same here in IE7, IE8 and FF.
