Just guessing here but I think the problem is not so much the Flash (since Flash will work just fine with FF) but how the buttons are placed on the page with AC_FL_RunContent. I’m not much on .js but from what I see in the file,
// Detect Client Browser type
there’s nothing about detecting FF . . . could be wrong about that but since it doesn’t work with FF. . . maybe.
So here are some alternatives:
A second alternative would be to use another method of placing the Flash buttons on the page(not AC_FL_RunContent), try swfObject (Google for more info).
Best of luck to ya on your project!
