My flash install is showing 616 both in the binary and as reported
from "about:plugins". 

When I've had reason to look at this the past things were always in
sync. My standard approach is to make certain that all instances of
my FF version that uses flash are closed before I install from the
adobe repo. I've never had to uninstall/reinstall the plugin.

I agree with generally trying to avoid flash (and cookies and
javascript) so have different FF versions and instances that I use
based on what is needed and what I'm willing to allow a site to use.
