Firefox - Can't find icons.png files

What steps will reproduce the problem?

1. Directory Structure:

html> ls
susy

html/susy>ls
data           green.png    info.php     susy.php
blue.png       img          script       red.png

html/susy/data>ls
blue.png       G.kml        green.png    L.kml
red.png        U.kml

html/susy/script>ls
geoxml3.js     susy.js

html/susy/img>ls
blue.png       green.png    red.png

(Icons everywhere testing...).

2.  kml Structure:
...
<Document>
    <StyleMap id="ok">
        <Pair>
            <key>normal</key>
            <styleUrl>#ok_icon</styleUrl>
        </Pair>
    </StyleMap>
    <StyleMap id="alarma">
        <Pair>
            <key>normal</key>
            <styleUrl>#alarma_icon</styleUrl>
        </Pair>
    </StyleMap>
    <Style id="ok_icon">
        <IconStyle>
            <scale>0.5</scale>
            <Icon>
                <href>blue.png</href>
            </Icon>
        </IconStyle>
        <LabelStyle>
            <color>ff7fffff</color>
             <scale>0.5</scale>
        </LabelStyle>
    </Style>
    <Style id="alarma_icon">
        <IconStyle>
            <scale>0.5</scale>
            <Icon>
                <href>red.png</href>
            </Icon>
        </IconStyle>
        <LabelStyle>
....

Tested with different hrefs:
./icon_name.png
../img/icon_name.png

3. susy.js:

...
geo.parse([G, U, L]);

for (var i=0; i < geo.docs.length; i++) { geo.hideDocument(geo.docs[i]); }

var aux;
switch(N){
    case "G":
        aux=geo.docs[0].url;
        window.alert(aux);
        geo.showDocument(geo.docs[0]);
        break;
    case "U":
                aux=geo.docs[1].url;
        window.alert(aux);
        geo.showDocument(geo.docs[1]);
        break;
    case "L":
                aux=geo.docs[2].url;
        window.alert(aux);
        geo.showDocument(geo.docs[2]);
        break;
    default:
        break;
...

What is the expected output? What do you see instead?

I see the map without icons.
And a console error: "Token sin cerrar" (Token not clossed)

What version of the product are you using? On what operating system?

kmz branz - r123
(ubuntu 14.04)

Please provide any additional information below.

Related to issue 107: with Firefox the output of the window.alert is correct!! 
(G, U, L in every case).
The kml files are found but the icons not.
(I suppouse...)
