OK I noticed just a small mistake in the above code this has now been fixed, and I'm pleased to say that the code below should work for all version of vShare and Firefox:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="550" height="140" id="recently viewed videos" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="recentplayer.swf?x=recentlyviewed.php&t=Videos Being Watched Right Now..." />
<param name="quality" value="high" /><param name="bgcolor" value="#ffffff" />
<embed src="recentplayer.swf?x=recentlyviewed.php&t=Video s Being Watched Right Now" quality="high" bgcolor="#ffffff" width="550" height="140" name="recently viewed videos" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>
Cheers Gary for making me aware of my mistake.. !
