Bing Animated Background not working in FireFox?

[Bigmike]

Ive tried diabling all the addons then reenableling them one at a time and in different ones independtly.

And Ive updated Silverlight,Adobe flash player.

I've also tried resetting Firefox and uninstalling and reinstalling it.

none of the above worked so why isn't Bing's animated background working on my Firefox. It works fine in Internet Explorer.

I was just googling this same thing because I noticed IE shows an animated bing.com homepage. Viewing the properties of the bing.com page it shows that the video is of filetype ogv which is an ogg video file. These should work in Firefox. A post on StackOverflow helped explain it. The video file is playable but in the source code of the web page Microsoft wants a certain video codec to play it which firefox doesn't recognize.
For today's background I viewed the source of bing.com and the url for the video background is
http://www.bing.com/az/hprichv/LavaWater..._EN-US.ogv
in the source code when they have that link it has this codec information in front of it to play it with theora/vorbis codecs & firefox isn't handling those meta tags. If you copy that direct link from above in Firefox it plays fine & then when you go to bing.com since it has now downloaded the file it plays. I think it's just that the site developers (of Bing) got it to work with IE9 and higher but didn't think about Firefox browser. Searching a little more I found on Mozilla's site where they mention "yeah, all of us (IE, Firefox, Chrome, Opera, etc) never really agreed on this codec tag thing so it isn't very universal."

var g_vid =
[["video\/ogg; codecs=\"theora, vorbis\"","\/az\/hprichv\/LavaWater_GettyRR_111842335_EN-US.ogv"]
,["video\/mp4; codecs=\"avc1.42E01E, mp4a.40.2\""
,"\/az\/hprichv\/LavaWater_GettyRR_111842335_EN-US.mp4"]]
;;hpResize(_ge('vid'))
;;g_img={url:'/az/hprichv/LavaWater_GettyRR_111842335_EN-US1232067134.jpg'

... I'm not a programmer but I think it tries to play it in ogv video, if that doesn't work it tries to play the video as mp4, if that doesn't work it falls back to showing a jpg picture


Long story short:
I figured out how to eventually get it to work but I'd have to view the source code to find the link to the file, go directly to that link for it to play, & then it'll play from the main bing page since it's cached.

Answer: there'd have to be a firefox add-on that strips codec tags out of html5 video souce code in pages you visit
or
Mozilla makes Firefox recognize those tags
Bing takes the tags out so everyone can see the animations.
