the problem is with the latest ( v10 ) of flash, it breaks plenty flash applications at present and is the main version why I have stopped using flash for the time being.
Have you thought of alternatives to create slideshows for example mootools?

the links above should get you started on flashless slideshows
below is a link to completly remove flash from firefox and then do a clean install
http://kb.mozillazine.org/Flash
hope this is usefull
I would still suggest giving mootools a go, since flash always give problems lately
ps i cannot see any flash other than by looking in the source, so if it is critical to your business I would not put it in flash, and if it is only for decoration ... do you really need it?
the code from the last flash i used

p.s I used the fullview domain for property afterwards
