Hi Ken,

In the address bar (also location bar or URL bar) when I type:
about:addons or about:plugins

I can see the version of flash being used by Iceweasel and in my case it is: Shockwave Flash 11.2 r202.

And in Chrome when I type:
chrome://plugins/

it shows me Adobe Flash Player - Version: 16.0.0.305
Shockwave Flash 16.0 r0

So am guessing Ice-weasel is unable to play the stream due to the flash version not being the very latest as in chrome.

Thank's - Aruna
