Conveyor Belt doesn't move in Firefox

[Butterfly]

I have several webpages with a Conveyor Belt.

I can only get them to move in IE, Chrome and Safari, but not in Mozilla Firefox.
Strangely I did create and publish a testpage yesterday using the exact same layout and images and it DID move in Firefox.

Here is one of the links:

Anyone got any ideas? I would love it to work, it looks great.

Have you cleared your cache and cookies in FireFox? If not then do so and before you open that page again, republish then open it with Firefox.

I have tried that, no luck unfortunately.
