After downloading the latest Windows updates I found that I could not play videos on YouTube or at other sites. Switching to other browsers I found I could play those same videos now without any problem. So I did a System Restore to determine if the Windows updates had affected video play using Firefox. The restore point was set to the day before the Windows download occurred. After System Restore was completed I could now play videos using the Firefox browser.

To make sure that the Windows update was the problem, I again downloaded the newest Windows Updates and once again could not play videos on any site using Firefox. System restore was used to again reset my computer to the day before and once again the videos would ow play in the Firefox browser.

Actually your reply took me in another direction and I found this on the Adobe site:

The RealPlayer extension for Firefox, Downloading & Recording, has compatibility issues with Flash Player 11.3. If RealPlayer is installed Flash Player content does not appear. YouTube provides an error message when you try to watch a video.

As a workaround, do the following: 

   Start RealPlayer.

   Click the RealPlayer icon in the upper-left corner and select Preferences.

   Select Download & Recording in the left menu and deselect Enable Web Download & Recording for These Installed Browsers option.

   Click OK and restart Mozilla Firefox.

Once I followed this I could now again play videos in Firefox.

The most likely cause is the latest Flash update. Please see this article for more information: Flash 11.3 doesn't load video in Firefox.
