Ubuntu fixing Firefox flash "This plugin is vunerable and should be updated"

Recently Firefox wasn't working with Flash.  I was getting "This plugin is vunerable and should be updated."

For the life of me, I couldn't figure out what was wrong.  Finally did the nuclear option.

> sudo apt-get remove --purge flashplugin-installer
> sudo apt-get install flashplugin-installer

then restarted my machine.  All fixed.
