John -

This is actually due to a bug in FF for Mac. The root of the problem is the alpha transparency of the Menu's shadow. This bug is fixed in FF 3, but sadly there isn't anything that we can do to fix this problem with FF 2. The workaround is simply to turn off the shadow for Mac FF when you are positioning submenus over Flash content. Here is a an example:

This bug is also applicable to Firefox 2 Linux and Firefox 2 Linux, the menu goes under the Flash.

Any solution for Linux users ?

Firefox on Linux isn't one of the currently supported OS + Browser combinations for YUI: http://developer.yahoo.com/yui/articles/gbs/

You can try turning off the shadow as I suggested in my previous comment.

Thanks for your quite response.

It does not work even with the shadow turned off.
This apply to Linux FF2, FF3 and Konqueror.
