unable to download mp3 file in mozilla

[rambo12]

I am able to download mp3 audio file in IE, chrome but unable to download in Mozilla ff 12 version.

When click on save it downloads but in binary file instead of mp3 file. when click open with vlc option. it downloads correctly in vlc mp3 format but goes in temp folder. what is the point of save option.

Below is the code. I am using header('Content-Type: audio/mpeg');

 

<?php

    if(!isset($_SESSION))

{

  session_start();

}

 

    include("elements/connect.php");

 

$fname=$_GET['f'];

    $file= "music1/".$fname;

header("Pragma: public");

header("Expires: 0");

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");

header("Cache-Control: private",false);

 

    //header('Content-Type: application/force-download');

 

header('Content-Type: audio/mpeg');

//header('Content-Type: application/data');

 

   //header('Content-Type: audio/x-mp3');

header("Content-Disposition: attachment; filename=$file");

    header("Content-Length: " . filesize("$file"));

    header("Content-Description: Download");

header("Content-Transfer-Encoding: binary");

    //$fp = fopen("$file", "r");

    //fpassthru($fp);

    //fclose($fp);

// refer to file and exit

readfile("$file");

exit();
