HTML5 problem

[Maureen L Thomas]

I cannot view any HTML 5 video in Firefox.  I have the latest version 
from just a few days ago and still no HTML 5.  I am so tired of this 
crap.  I have tried various ad ons with no luck.  I have the latest 
Debian version and the newest version of Firefox.  What the hell have I 
done wrong this time?
