Hello, Has anybody succeeded in configuring Mozilla to handle FDF (form data for PDF)? PDF files open fine "inline". But I couldn't do this with a FDF data sent by the HTTP server as 'application/vnd.fdf' (and referring to the PDF files containing a form to be filled in). I have configured a new Helper application/MIME type for application/vnd.fdf, extension FDF. But Mozilla just tries to spawn Acrobat externally an dthen fails. Thanks, Sarunas Burdulis
