Why the hate on firefox?

So why can the html5 player not work in firefox? Firefox now supports it through OpenH264 and I can run video's from literally everywhere else just fine except here on giantbomb. Which is a shame since I can get video's working here just fine if I edit the html. Just messing around with the following and...

<div id="js-vid-html5-player20641386">

<video id="uvpHi5" width="100%" height="100%" poster="/bundles/phoenixsite/images/core/loose/clear.gif">

<source src="http://vidtech.cbsinteractive.com/h5/blanks/uvp_blank.mp4"></source>

</video>

</div>

So basically after I hit play the source just goes to this blank looping video. Furthermore, I can replace the src to a proper video (i.e. http://v.giantbomb.com/2015/07/31/vf_tembothebadasselephant_ql_07312015_4000.mp4) and it will still not work for me. BUT if I remove the poster from the video line I can then see the video, show controls and play the video just fine (I assume the poster is just an overlay on top of the video?).

I would also like to note that it seems even w/o a premium subscription I can still find the links to the videos in the html and play them just fine???
