Topic: Gallery display problem with firefox flash SimpleViewer

I have a problem with SimpleViewer and firefox. Indeed, the gallery appears well with Internet Explorer but not in firefox. The buttons, boxes appear but not images (or thumbnails or large), which is puzzling ...
I generate the gallery with SimpleViewer lightroom 2, I traveled the forums but impossible to find a solution. Yet with firefox when I go to the site SimpleViewer here galleries demos work correctement.Help me please.
Thank you very much
