Please share more details like your OS, browser, and how this "an add on for this website" error message (you think) is connected to Flash Player so that we can help you.
Thanks for responding. The original issue started when trying to veiw a youtube video and a foxnews live stream. It stated I needed to update my adobe flash player so I did. I successfully installed the update. But still was not able to see the video or stream. Thats when I started seeing the error stating that an add on for this website failed to run. My OS is Windows Vista Business, my browser is IE9. If you need anymore info please let me know. Thank you again for your assistance.
