How to get HTML 5 videos to play on Youtube.com

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?

As far as I know, it's not possible to get HTML5 video on all YouTube videos without an add-on (no, the dusty old HTML5 trial option doesn't help).

I use the following. Its settings are at the default, except for YouTube video loading method which I set to Player API (because the default stopped working).
