Hey Devo -- Nice surf video! The video's properties says it's Windows Media Video 9.
My Windows did a big auto update in early December that left my installed Firefox version dead in the water. Just now I researched
Firefox updates -- I don't know that you can bet the auto-update feature will take care of everything all the time. But what worked very well for me in early December was stumbling across the beta site for Minefield, the version of Firefox that's supposed to work with Vista.
Here and
here. I installed Minefield and it copied across all my favorites and bookmarks. It's been working flawlessly on my Win XP system -- better than before I would say, although it's had to update about twice a week.
