327948 - Mozilla ignores "Always perform this action when handling files of this type" setting

Status: RESOLVED DUPLICATE of bug 236541

(SeaMonkey :: General, defect)

Description

[Tristan Miller]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050919
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20050919

I have Mozilla configured to always save to disk files of the MIME type application/x-bittorrent.  When I click on a hyperlink to a bittorrent file, Mozilla correctly identifies it as an application/x-bittorrent file, but opens a dialog saying that "the site has suggested that … be handled as an attachment" and asking me what I want to do with the file anyway.  This happens only with certain websites, so I assume that the bug is triggered by something the web server is sending.  With other websites, clicking on a torrent link simply opens the "Save file" dialog.

Reproducible: Always

Steps to Reproduce:
1. Edit->Preferences->Navigator->Helper Applications
2. Add or modify the entry for application/x-bittorrent so that "Save it to Disk" is selected in the "When a file of this type is encountered" frame.
3. Go to <http://ts.searching.com/torrent/484766/Buster_Keaton_shorts_public_domain>
4. Click on the "Download torrent" link
Actual Results:  
5. The following dialog window pops up (see attached screenshot).  The last line (Always perform this action…) is inactive.

Opening Buster_Keaton1.avi.torrent

The site has suggested that "Buster_Keaton1.avi.torrent" be handled as an attachment.  It is of type application/x-bittorrent (Bittorrent download) and is located at: http://ts.searching.com.  What should Mozilla do with this file?

( ) Open it with __________ [Choose…]
(*) Save it to disk

[ ] Always perform this action when handling files of this type

Expected Results:  
5. Mozilla should have opened the "Save file" dialog immediately without prompting me for what to do with the file.

I guess the problem lies with whether the server is suggesting that the file should be "handled as an attachment".  I'm not really sure what this means, but it doesn't make much sense to me in the context of a web browser.  When I specify in the "Helper Applications" configuration dialog that I want a file type to be always saved to disk, I don't care what the server suggests; it should be saved to disk regardless.

An example of a website with an application/x-bittorrent link that does not exhibit this behaviour is <http://librivox.org/frankenstein-or-modern-prometheus-by-mary-w-shelley/>.  Clicking on the link "Bit Torrent of the entire book" <http://librivox.org/torrent/torrents/AUDIOBOOK%20Frankenstein%20or%20Modern%20Prometheus%20-%20Mary%20Shelley%20%5BLibrivox%5D.torrent> opens the "Save file" dialog as expected.

This is already fixed on the trunk.
