How to name a file for download on Firefox?

Question

The following headers work on IE but not on FF

<%@ Page Language="C#" ContentType="text/csv" Inherits="System.Web.Mvc.ViewPage"%>
<% Response.AddHeader("Content-Disposition", "filename=report.csv;attachment"); %>

In FF the suggested name in FF appears as "report" without the extension.

Answer 1

try "attachment; filename=\"report.csv\"" (i.e. with quoted filename)

Answer 2

filename is just an parameter of Content-Dispostion. So you have to swap both:

<% Response.AddHeader("Content-Disposition", "attachment;filename=report.csv"); %>

Answer 3

This question about CSV generation helped me when I needed to implement CSV generation and download: How do I best generate a CSV (comma-delimited text file) for download with ASP.NET?

Answer 4

I am currently using code that looks like this:

response.AddHeader("Content-Disposition", "attachment; filename=\"data.csv\"");

In my daily work - and that works just fine. Also are you sure this is not your OS or anything that has the "Hide extensions for known file types"-option enabled? (I know Windows have this option and it drives me crazy)
