F9: How to replace 'swfdec' with Adobe's Flash Player?

[Dan Thurman <dant cdkkt com>]

I got the swf player to work in F8 but I am unable
to get the player to work in F9 Firefox 3.0.

I noticed that the underlying player is swfdec 0.6.0, but
when I checked on F8, it is adobe's Flash.  Why is it
that I cannot seem to replace swfdec for adobe?  And
yes, I tried Firefox's edit->preferences->applications and
selected 'Shockwave Flash' but nothing happened - swfdec
still appears. And of course, the adobe's flash is installed
but not macromedia's shockwave, which is not supported.

Thanks-
Dan
