It doesn't work for me either. The site tries to implement a Flash fallback and WebM, but the resulting video ends up H.264, which is currently not supported by Firefox. It's possibly broken by one of the fifty trillion ads and tracking scripts that are blocked on that page, but I won't disable Adblock Plus to find out.

You can right-click, choose View Video, then select to open it in Windows Media Player (on Windows 7), MPC-HC or VLC.

Thanks for the hint. It seems their detection script chokes on 64-bit Windows. If I fake my user agent string to say 32-bit Windows, then it works fine: if Flash Player is enabled, the videos will play through it, and it it's disabled, then the WebM videos will play instead.

The problem has to be reported to the site. If they refuse to fix it, you can work around it using the UAControl extension. Set the user agent string to your current one, minus the WOW64; bit:

Code: Select all

Hello Gingerbread Man!

I'm one of the developers of this site. Can I ask you to post you whole user agent so I can fix this? You can use: http://whatsmyuseragent.com/ to get user agent.

All registered users who are logged in can see the user agent strings at the bottom of every post. If you want to see what mine was when I tested your site, simply scroll up:
64-bit failed | 32-bit worked
