MetaStream 3 is listed as one of my add-ons. I believe it was used for videos. Since it was disabled, I have not been able to view YouTube and other video types. I get the message "The plugin for this content has been disabled. Click here to manage your plugins."

The plugin you need is Flash. Go to Tools > Add-ons and select the plugins tab (the lego-block) and enable things.
