874072 - Firefox plays .mp3 file instead of downloading it.

Status: RESOLVED DUPLICATE of bug 861090

(Core :: General, defect)

Description

[Serious Tom]

User Agent: Mozilla/5.0 (Windows NT 6.2; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130511120803

Steps to reproduce:

I have a website that I take care of and I upload .mp3 files to it. On the website you have a choice to either click on a Play button to listen to the mp3 that links to a .m3u file to stream it. The other button is to download it and it links to the .mp3 file.


Actual results:

The link for downloading now just opens a new page, that doesn't exist on my website and plays the .mp3 instead of downloading. The page is the path to the linked .mp3


Expected results:

It should have just downloaded.
You can test it here, just click any download link.

This was all working just last week before updating to Firefox 21.

You need to configure your server to set the field Content-Disposition so the user will have the choice to download the file or use it:

Or just put a "download" attribute on that <a>.
