DA, watch that thinking while eating lunch...it's bad for the digestion! However it is much appreciated. Below are the answers to your questions. 1. Have you tried FF bare boned with not add-ons to see if this occurs? Ans. Yes 2. Have you tried a prior version of FF? Ans, Yes, just a few minutes ago. I un-installed ver 11.0 and installed the older 10.0.2 in it's place. I also un-installed Flash Player and re-installed that again. ...still the same results after shutting down and re-starting! 3. Do you have FF set to delete history when closing? Ans, No. Thanks, Horton.

Sapphires, Maybe the link below will help. Terry Here is a link that might be useful: Configure Firefox and Mozilla to display PDF files (Acrobat 8.0, Adobe Reader 8.0 on Windows)

This is just one reason I seldom use Firefox. Seems they've had lots of problems lately with add-ons, apps, and other necessities. I mostly have used Chrome and just do not have these sorts of problems.

camp56, damccoy,ravencajun, and stargazzer, Thank you for the quick responses. Below are my answers to the questions you have asked. The browser is IE8. The version I downloaded yesterday was Adobe Flash Player 10 ActiveX. I uninstalled it, and downloaded and installed it again. Using START> Control Panel>Programs and Features I confirmed what I re-downloaded was Adobe Flash Player 10 ActiveX. The system I have is 32 bit. After downloading and installation, I still could not see any animation. I went to the sites that ravencajun suggested, went on YouTube too, saw nothing but the same dreadful messages " You don't have current Adobe Flash Player", or "cannot find Adobe Flash Player". I have not try Safe Mode yet. Will it help? How can I get to it? Thank you again for the help.
