html5 video & firefox

[David Brownlee <abs%absd.org@localhost>]

Is anyone using firefox to view html5 video content - specifically
youtube videos?

As a test I went to http://www.youtube.com/html5 to enable youtube html5, then
tried viewing a video:

which gives a segmentation fault.

This was on NetBSD 5.99.54 amd64:
