I go to http://www.youtube.com/html5 and enable html5. I do not get any video tags or content of the sort.

If I do a search: http://www.youtube.com/results?search_query=gods+gonna+cut+you+down&aq=0&webm=1

None of those videos will appear with the video tag. It will all be adobe flash even though I don't have flash installed. Youtube used to work great with firefox4.0.

The problem is with your user agent. it is:

Mozilla/5.0 (X11; Linux x86_64; rv:2.0b8pre) Gecko/20101111 Firefox-4.0/4.0b8pre

While it should be:

Mozilla/5.0 (X11; Linux x86_64; rv:2.0b8pre) Gecko/20101111 Firefox / 4.0b8pre

I have the same problem, and while I do not know its cause, I have found a workaround- install user-agent-switcher..... Have you installed firefox-4 with the "daily" ppa too?
