I am in shellshock. I finally broke through and was able to watch video on FoxNews, WSJ, and CBS, which were web sites I had been unable to watch.
I had been to Adobe Support before but tried again. The following URL helped. It seems to be for online games.

I skipped the information on 'clear cache' because steps don't work on my Safari and Foxfire browsers. I had already reset Safari anyway and I think that clears the cache.
I did not take my computer off its wireless connection. If instructions were focused on game playing, I ignored them.
I had already done the upgrades so I skipped all that.
At the instructions on "Settings Manager " for Flash Player, I paid close attention. I didn't realize you needed to make your settings and permissions on the Adobe website (or through this embedded settings manager) and I had been checking my permissions in the Flash Program in my computer system preferences.
The steps that I took and that helped me were these:
1. Control Click (Right Click) on any content that is displayed in Flash Player. For me it was the black video screen.
2. Select Global Settings. The Settings Manager Help Page appears.
3. I checked:
"allow third party Flash content to store data on your computer".
"Ask me when a site wants to use the camera or microphone (recommended)."
4. I gave them 1 MB of storage. I tried 100 KB but that did not allow the videos to play.
I enjoyed watching videos I had previously not been able to watch.
I have since gone back and changed the Settings Manager to "Ask me before allowing new sites to save information on this computer". I did this on my computer systems preferences so it may not mean anyting. I then clicked on 'LOCAL STORAGE SETTINGS BY SITE' and selected the sites I wanted to give a permanent permission and checked "Allow" for them.
Thank you to all those who supported me and tried to help me through this extremely frustrating time.
