Q: suddenly no video will play off the internet

I am running Mountain Lion and have had to restart in safe mode to use airport card and today NO video will play.  Not YouTube not even the Williams sisters on the Apple Iphone5 video on the apple site.  There must be something wrong but I don't know what.  Can anyone help me?

thanks!

MacBook (13-inch Aluminum Late 2008), OS X Mountain Lion (10.8.2)
