I have added a embed tag with a .swf file which reproduce a .flv video. The thing is that it works fine in all browser except Firefox. i tried to debug it using firebug, and what i found is, that aditing the embed using firebug without modifying the code just adding a space after the embed, the video start displaying.

Can you post a link to that web site or post a relevant part of the code?

I've run into a similar problem with YouTube videos which I've been able to fix with a Greasemonkey script. (Videos on the home page of YouTube lack a wmode attribute and Flash video renders as a grey box without it. I found that by adding wmode through Firebug the video would start to play.)

To get the script to work, I had to force to the browser to reload the element, which is what appears to happen when editing in in Firebug.

This affects me in Firefox 3.6 and 4.0 (Ubuntu Linux 10.04).

Greasemonkey script:

// ==UserScript==
// @name           YouTube fix
// @namespace      http://lukemorton.com.au
// @description    Set the wmode attribute for YouTube videos
// @include        http://www.youtube.com/watch*
// ==/UserScript==

var allEmbeds, thisEmbed;
allEmbeds = document.evaluate(
    "//embed",
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);

for (var i = 0; i < allEmbeds.snapshotLength; i++) 
{
    thisEmbed = allEmbeds.snapshotItem(i);
    thisEmbed.setAttribute('wmode', 'opaque')
    thisEmbed.parentNode.replaceChild(thisEmbed.cloneNode(true), thisEmbed);
}


Whilst not particularly elegant, you could probably adapt this method to work for you. If you insert the script below after the embed it should work (note that I haven't tested this):

<script type="text/javascript">
var allEmbeds, thisEmbed;
allEmbeds = document.evaluate(
    "//embed",
    document,
    null,
    XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
    null);

for (var i = 0; i < allEmbeds.snapshotLength; i++) 
{
    thisEmbed = allEmbeds.snapshotItem(i);
    thisEmbed.setAttribute('wmode', 'transparent')
    thisEmbed.parentNode.replaceChild(thisEmbed.cloneNode(true), thisEmbed);
}
</script>


The above code will set wmode for all embeds in the document. If you'd rather target just the movie in your code, you could use this:

<script type="text/javascript">
thisEmbed = document.getElementById('mediaPlayerMz');
thisEmbed.setAttribute('wmode', 'transparent')
thisEmbed.parentNode.replaceChild(thisEmbed.cloneNode(true), thisEmbed);
</script>


Sorry about all the links, I couldn't find a way to disable them (<nowiki> doesn't seem to work).
