We are using SWFObject on this page to load the flash and it works fine in every tested browser combination other than Mac with Firefox.

I've seen some posts about this but none of the suggestions worked for us. Does anyone have any further ideas on why this would be happening or can you point me toward some troubleshooting steps I can take?
The code seems ok to me, and it is working as intended in FF for PC. Do the SWFObject test pages work as intended on your mac? If they do, strip your page back to just the swfobject code (kill off the other JS and unrequired CSS etc) and see if it displays as intended. Build up the page again by adding stuff back, and if it breaks at any stage, you have your culprit.
From my understanding (second-hand), on FF for Mac the SWF just doesn't show up at all. The SWFObject test pages do work with that combination, so we will have to test as you suggested. I'll post the culprit here in case anyone else has the same issue.
Thanks again for the help (and the note on PNG fix).
