title: TYPO3 - How to prevent FTP 150 alert
body: <p>I always get this alert before downloading a file or loading my page where I provide a file for download which is stored on a FTP server. It must be related to the extension <strong>FAL_FTP_Driver</strong> because the alert does only appear since I upgraded from 1.2 to 1.3. But I also get it after changing to 1.2 again which is strange.</p>
  
  <p>I already checked the permissions of the folder and files on the ftp server.
  It is set to <code>drwxr-xr-x</code> for folders and <code>-rw-r--r--</code> for files. They all have <code>root root</code> as user and group.</p>

  <p>Does someone know how to prevent it? 
  The alert shows on firefox (with ubuntu and mac) but does not appear on chrome (mac)</p>
