Can't watch videos from getting started on 16.0.1 install page with Mac Intel 10.6.8 - no mp4 plugin update?

Page "Getting Started" for Firefox 16.0.1 has a video window that plays audio only. Test of Firefox for the plugins page shows RealPlayer, Flash, Flip4Mac and Java are up-to-date. What other video plugins are required. I am currently using Firefox 10.0.2 and I am not inclined to update unless I have good reason to do so.

If that doesn't work in Firefox Safe mode then disable all extensions (Tools > Modules > Extensions) and then try to find out who is causing by allowing an extension at a time until the problem reappears.

Close and restart Firefox after each change through "file > exit ' (Mac: ' Firefox > leave";) Linux: "file > exit ')
