Recently active problems in SlideShare tagged with embed

Hi, I am embedding slideshare presentations for others to view. The View on SladeShare button does nothing on click for me in either Safari3 or FF3. I tried disabling popup blockers, and no change.
Here is an example of the embed: http://zeb.tumblr.com/post/38926148/w...
Here's a motion capture showing no action when the button is clicked:

I recently made a slidecast. When I play it on Slideshare it works fine. When I try and play it (and other slidecasts) embedded on a wiki, it will not play the audio. Any ideas? Am I doing something wrong or will this eventually fix itself?

My embedded slideshows are not working firefox but working in IE7. What is the problem? I copy pasted the code from your website. How do I make this work? Please help.

youtube plays embedded videos on personal websites, so I was in the impression that your site does the same. I am using firefox browser.
