Try the new version of Accessible YouTube. It works in more browsers and even on the iPad and iPhone.
Welcome to Accessible YouTube, an interface to YouTube designed for people who access their computers via either 2 switches or a mouse. It allows the user to use two keys/switches or a mouse to navigate through a list of videos, and watch any or all of them. Currently the list of videos can be a playlist, the results of a video search, the related videos for a particular video, or YouTube's most popular videos. For now, you must use Firefox in order for it to work. You can download Firefox for free here.
Note the little home icon in the upper left corner of the page. Clicking it will bring you back here.
Warning: This interface allows unfiltered access to YouTube videos, some of which are not appropriate for all viewers.
