Keynote, Firefox, Chrome & IE Question...

I have exported a presentatin I created and uploaded it to my site and it only works in Safari. I have read that the animations and what not are limited in any other browser but Safari, but can't seem to find much info on it.

Does anyone have more details on what works and what doesn't with the HTML exported versions of Keynote presentations in any other browser than Safari?

Thanks,
