With this in mind, I was hoping that Opera and, recently, Webkit support for SMIL would make a compelling case for adding the feature to Firefox. We have a bitrotted patch that has promise. But then I saw Jeff Schiller’s report on how well Webkit supports SMIL. A score of 5/116 isn’t very compelling, especially with Opera’s 110/116 score. Come on Webkit! I need you to support SMIL better than that!
