Image Fading Script working in IE, Chrome, Safari...not Firefox

Website is here:

The header at the top of the page has four pictures that fade. The script works well in all browsers except Firefox. This same script has worked on Firefox in the past. Does anyone have any guesses as to why Firefox wont display this correctly? I’m stumped. I didn’t write the script so I can’t troubleshoot it myself very well.

Thanks in advance to anyone who takes the time to look at this.

Hi,

The fade effect on your site is accomplished with the Tigra Fader JavaScript slide show.
The version of Tigra Fader you are using is quite old (07/23/2007)
Replace the Tigra Fader script (it is located here:[noparse]http://www.heritagechristianschool.org/templates/HCS-Main/tFader.js[/noparse]), with the latest version (available here: http://www.softcomplex.com/products/tigra_fader/download.html) and your site should work just fine in FireFox.
