For some reason removing Adobe Flash in the software center then reinstalling it in the software center fixed the problem. Thanks Jeremy.
fyi. Before removing and reinstalling it, I went back into Mozilla Firefox Tools, Add-ons and the Plug-ins tab. I clicked on the Find Updates tab and it opened a window to https://www.mozilla.org/en- US/plugincheck/. In this window it said that Adobe Flash had been removed for my safety. More accurately it should have said my inconvenience. Now it says that "Shockwave Flash" is an installed plug- in. Just a little info in case someone with Ubuntu wants to provide some feedback to someone at Mozilla.
