buttons on www.leidyschurch.org does not work with Firefox, but does with MS I.E

[MarioG]

Binary package hint: firefox-3.5

On the top third of the www.leidyschurch.org is a row of navigation buttons. With Firefox I cannot select those buttons. When I hover over them the pointer does not change. If I use Microsoft Internet Explorer I can select those buttons and navigate to those pages.
