Download File not opening correctly in Firefox... (Works fine in IE...)

Question

Running the following code snippet in Oracle 11.2, APEX 4.2.3, IE 10, Firefox 24:
procedure download_to_user
is   
t_excel blob;
t_filename varchar2(200);
  begin
  t_excel := finish;
  t_filename := 'test.xlsx';
   htp.flush;
   owa_util.mime_header( 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', false );
   htp.print( 'Content-Length: ' || dbms_lob.getlength( t_excel ) );
  htp.print( 'Content-disposition: attachment; filename=' || t_filename || ';' );
  htp.print( 'Content-Description: Generated by as_xslx' );
  owa_util.http_header_close;
  wpg_docload.download_file( t_excel );
  apex_debug_message.log_message( 'done' );
  end;
Now the strange part.. It works fine in IE & Chrome when I have it called from a button click on a form, when I try it in Firefox, it returns a garbled file that Firefox thinks IT Should open...  I would think since all the issues we seem to have with IE that this would be the opposite..
Thank you,

Hi TexasApexDeveloper,
I don't have IE10 to test this with but I find it strange that you don't need to add   
APEX_APPLICATION.stop_apex_engine;
or
APEX_APPLICATION.g_unrecoverable_error := TRUE;
at the end of your code, to stop possible branches or further rendering.
That's the only thing in your code that I can see that can indicate an error. Can you create an example on apex.oracle.com if that does not help?
