We currently have the same problem. It seems to be a crossdomain issue
specific to Firefox on Windows. If you serve your swf from the same domain as
your site, notice it will work again. (Your site is www. but the swf is hosted
at site.)

This is becoming a huge problem for my company as all static assets are
required to come from a different sub-domain as they are edge cached via
Alamai.

Anyone else having this problems? Any potential solutions?

Try setting param "allowScriptAccess" to "always", seems to fix the issue.
