Html5 Plugin For Firefox

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. 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.

In Firefox I can only use Silverlight to view Amazon Instant Video (.) Actually (if the information I'm providing you is not outdated/obsolete) you can use Flash as well. Quote (with modification by me): Amazon Instant Video prompts me to install Silverlight, but has a link [, idk ()] to a Flash version of their video player, which still works just fine. OP, I see you mention Internet Explorer, so I assume you're on Windows, in which case this information might be useful to you if - I know you'd prefer HTML5, but as that's currently not available to Firefox users apparently - you might prefer using Flash instead of Silverlight.
