The current Shockwave flash player plugin for Firefox:
NPSWF32_16_0_0_296.dll
is labeled in file Properties as:
Shockwave Flash 16.0 r0
This is causing Firefox to think it is not a current version, vulnerable, and thus firefox is blocking it.
We need Adobe to correctly label the file properties and make that correctly labeled file available for download.
It is causing an endless loop right now in Firefox where it says the file isn't current, yet it is.
