It looks like I got the problem resolved. I used REVO to totally remove FF and all references to it, including personal settings. I opened I.E and browsed the web and all worked well. I.E. is using the FIREFOX version of FLASH PLAYER 10______.34 which I manually installed into I.E. and it accepted. I then ran the install for FireFox 5.0 As it was loading it asked me if I wanted to import settings from I.E., I opted YES, I was then asked if I would like to make FF my default, I opted YES. Once done and without making any changes or additional additions or actions of any kind, FF imported everything I had in I.E. I went to several sites I knew Flash Player would be needed and everything worked fine. It appears as I suspected, there was a toggle somewhere in FireFox that got toggled to either TRUE or FALSE. I wish I could have determined which one, to have made this problem go away sooner. If time permits, I may play with them until I can recreate the problem. Thanks much to all of you who responded and were so willing to give up your time and effort to help me.

Worked OK for me and I have version 10 Flash Player too. Try shutting down the computer and restarting. How long as this been happening? Here is a link that might be useful: Mediaface

If you using firefox to view the Videos try using IE and see if the problem goes away.

Thanks for the responses and help. I am not using antivirus and removed the the antivirus before my Adobe problems. I checked/installed updates to Windows and IE. I went to Adobe.com and installed/reinstalled. This morning the issues seem partly fixed. When I am on a web page, such as Yahoo, whether in IE or FF, some of the boxes display and some don't. If I go to a web page page, like Yahoo's tech page, that has mostly boxes that have videos in them, I see the text in the boxes but they are otherwise blank. If I click on the box a video then starts playing. I know this isn't how it's supposed to work, but it's better than it was yesterday. Maybe if I wait till the next Adobe or Windows update it will sort itself out? Thanks for the suggestions. If you think of anything please let me know. I think I will put this laptop away for a week or two and use my Win7 laptop instead. I'll check on updates the next time I get it out and hope for the best.
