I am trying to go without Flash and enjoy HTML5 video, but I am running across a strange problem.

Embedded YouTube videos play just fine in FF, but if I try to view the same one on the YouTube.com page, it asks me why I haven't installed flash yet.

Is there a setting to change to have FF ask YouTube to play in HTML5 no matter what?
