By default, this option is off in Firefox, so the browser is not able to play some HTML5 video streams. Those videos require the Media Source Extensions feature which is disabled by default in Firefox. RECOMMENDED: • Open the Firefox browser and type the following in the address bar: about:config Note: A warning page may appear that says 'This might void your warranty!' If you prefer HTML5 videos over the Adobe Flash Player, you might want to enable Media Source Extensions to get advanced support of HTML5 videos in Firefox. 
It supports the required HTMLVideoElement, but some videos do not play anyway.
UPDATE UPDATE UPDATE!!!!!!!!!!!
I really didnt think Id see this kid again.. but he's trying to break into video I guess.
>-----(im sending Eru G his email addy..)<-------
after 10 minutes of shooting the shit I finally went CSI.
I asked him is his SSL had crashed yet from having a pirated copy..
he said (like many said) that he has a proper version of SSL.
it was the video plugin serial that he had got.
so I continued down this road..
(just so people dont come here looking for how to get serials im not going to post
the exact conversation..)
but lets just say im sure serato can weed out these people quite easy once they know they exist ..
we ALL KNOW serato got their security on lock and I dont want to jeopardize that.
so, I am sorry I lead people to believe he has SSL.
but, that is what he said..
I didnt go into a long diatraub about ethics..I just told him is was a dick move, and is 200.00 really worth playing with fire..
and what came back:
'I dont like it anyways.. VDJ has sync so I can do other stuff with the videos and not worry about the mixing..'
no lie.
