The page source show a different src (intrinsic%20captures.swf) for Firefox in the embed then IE see in the object param movie (intrinsic.swf)
So you need to change that and make both SWF links the same.

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
 width="800" height="630" id="tech" align="middle">
<param name="movie" value="intrinsic.swf" />
<embed src="intrinsic%20captures.swf" quality="high" width="800" height="630"
 name="tech" align="middle" allowscriptaccess="sameDomain" type=
"application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object>

cor-el,

Thank you for taking the time to help me, much appreciated. You were correct in your finding. I have changed the source code and FF now sees the new video.

But, now that it's corrected, FF does not play the midi file. It does play on IE and did play before I changed the Flash file code. Do I need a different code for midi files on FF? Any help would be appreciated.

Thanks again for your time.

Bob

You can add a type attribute to the EMBED tag to make Firefox use a specific plugin.
If you use type="application/x-mplayer2" then the WMP plugin will play the file.
It is also better to move that code to the BODY section instead of placing it in the HEAD section (Firefox will move it to the body anyway).

<EMBED src="Ave_Maria_Bach.mid" type="application/x-mplayer2" autostart=true
 loop=true volume=100 hidden=true><NOEMBED><BGSOUND src="Ave_Maria_Bach.mid"></NOEMBED>

Thank you for your reply ........ I added your script into the body but still no music on FF. It still works on IE though. Maybe I did something incorrect?

I'm not on Windows, so can't test if the WMP plugin can play the file.
I do not have a plugin on Linux that plays MIDI files embedded.
You can try to install the new WMP plugin to see if that plugin can handle the file.

The embedded midi file plays fine in Firefox 4 on Windows 7 with the new WMP plugin.

My next question was going to be if I might be missing a plug-in ......and I was. This last message of yours fixed the problem for me on FF.

I really appreciate your help.....I would have been trying forever to solve this on my own.

Thanks again,

Bob

Thank you Alice ......I finally got it to play on my computer using FF. I appreciate you taking the time to write.
