This page does verify that I have the latest Flash Player:

... which is (as of Sept.08, 2016)
YOUR SYSTEM INFORMATION
Your Flash Version 22.0.0.209
Your browser name Firefox (NPAPI)
Your Operating System (OS) Windows (Vista)
However, this page:
http://www.adobe.com/software/flash/about/
is unable to detect the Flash Player.
I do not know why. Just thought I would let you folks know.
I am running Vista(64-bit Home Premium) on a Gateway FX6800-03h desktop.
This is the first real oddity that has shown up, with Flash Player, in over four years.
It does seem to be working though.
==========================================
By the way; the rigmarole to get to this point to ask a simple question is by far a great way to signal a downward support trend.
I was just trying to give you people a heads up on a potentially bad problem.
