SWF loaded twice in Firefox, workaround needed

Question

I have the same problem as the following stackoverflow question:

• http://stackoverflow.com/questions/499949/flash-loads-twice-workaround

but the provided solution is not working for me (my script runs after the DOM ready and a delay), is there any workaround to fix the Firefox bug which is fixed in the bugzilla but still exists?

update: I'm using DOM functions to create the <object> as swfobject does.
