Amazon Instant Video & HTML5
It seems that in FIrefox (and IE) I can only use SIlverlight to view Amazon Instant VIdeo, whereas in Chrome it uses Amazon's new HTML5 player.
Html5 Video Player Plugin For Firefox
In Chrome I had to install a DRM Plugin (Widevine CDM) so I installed the same in Firefox from their website but still with no joy. I don't want to use the Silverlight Player but it seems that Amazon's site is forcing Silverlight as even if I disable the plugin it says to install it.
Anyone got any ideas as to why I can't use Amazon's HTML5 Player? Both FF and Chrome have HTML5 DRM Support and YouTube's HTML5 player works just fine in FF.
I have searched around quite a bit but have not solved my problem.
I have a video tag running as follows:
I am using Jekyll for the URLs. They work fine.
The site is live at switzerlandllc.com. Click any video in FF and it shows an image and an X. Chrome and other browsers work fine.
If you grab the source of a video and load it in a new tab it plays fine. At least it does for me.

I have added:
Mozilla Html5 Video Player
to my htaccess file. I suspect that I don't need the .ogv or .webm.
I don't understand why loading the video URL will play the videos fine but loading the video into a video tag fails.
Any ideas?

This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.
Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:
I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.
Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Can crc calculator. Yay.
Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.
