Status: RESOLVED WORKSFORME

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b3) Gecko/20100805 Firefox/4.0b3 Glue/4.5

Joystiq uses a viddler code template for embedding their videos into the page, it involves an object tag with a video tag inside.

Might just be their site code, but I missed seeing anything obvious.

Setting html5.enable to false fixes the issue.

Reproducible: Always

Steps to Reproduce:
1. Visit URL
Actual Results:  
Page is considerably shorter than expected, right aside and comments missing.

Expected Results:  
Page appears as normal.

Had contacted Joystiq, they said its a problem they know about, but arent considering fixing it. I get the notion they think its a firefox beta bug, rather than expected parser in the future.

This happens to me as well on a Mac, so it's not platform-specific.

It appears to be from a missing </object> closing tag, below is a trimmed version of the code (without param & id)

<div><!--[if IE]>
<object width="599" height="357" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
  <object>
   <video src="http://www.viddler.com/file/e5820d21/html5mobile/" type="video/mp4" width="599" height="337" poster="http://www.viddler.com/thumbnail/e5820d21/"></video>
  </object>
</object>
<![endif]-->
<!--[if !IE]>

Shouldn't this have been moved to evang?

Yes.

Just a minor update on evang: I believe from my few emails & twitterings to Viddler, and a recent post on Joystiq ( http://www.joystiq.com/2011/02/09/how-bulletstorm-became-the-worst-video-game-in-the-world/ ) with a corrected embed block, that they have told their partners to update whatever templates they are using.
URL for this bug still shamefully shows the error, as I doubt joystiq will go back through their posts to correct.
