Strange problem with .php saving in Firefox

K, I’m trying to make a flash what saves text into .txt document. It works fine, but when saving text with firefox, firefox browser never ends loading, tough it saves the text. Works fine in IE.

AS:
[AS]
on (release) {
_root.neljateistkymnes_vastusaada_d = neljateistkymnes_vastuss_d.text;
pealkirid = _root.neljateistkymnes_vastusaada_d
loadVariablesNum(“save.php”, 0, “POST”);
nextFrame();

}

[/AS]

PHP:


<?php 
$fp = fopen("uudised.txt",  "w"); 
fputs($fp, "&pealkiri=$pealkirid");  
fclose ($fp); 
echo("<meta http-equiv=refresh CONTENT=1;URL=uudised.php>"); 

?>
