242634 - Firefox download ignores check box "Do this automatically for files like this from now on."

Status: RESOLVED DUPLICATE of bug 236541

(Toolkit :: Downloads API, defect)

Description

[Jared Thomas]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

When opening an image on a page generated by php, I get a window 
titled "Opening <filename>".

The text says "You have chosen to open "<filename>" from "<url>" which is a: 
JPEG Image. What should Firefox do with this file?".

There are radio buttons for "Open with" and "Save to Disk" and a check box "Do 
this automatically for files like this from now on."

Plus there's a note: "Settings can be changed in the Downloads section of 
Tools, Options."

I mark the check box "do this automatically..." and click OK. The image opens 
in the Windows default viewer.  A blank window/tab remains open which was 
intended to hold the graphic.

Now I open another image, same method -- generated php page. Or I re-open the 
same image. The "Do the automatically" is ignored, and I get the same window 
titled "Opening <filename>".

Looking at the list of file types in Tools / Options / Downloads / "File 
Types" "Automatically perform..." I see filetype JPG is listed to be opened with
jpegfile.  The "Opening <filename> box is always primed to "open with" 
(not "save to disk") as per the table.

Why doesn't Firefox start opening jpeg images automatically, as per the list?

Why can't Firefox display the jpeg in the window/tab the web page designer 
intended, as opposed to launching the windows designated display program?

This problem has been reported by at least 3 people on the forums.

Reproducible: Always
Steps to Reproduce:
1. Open the attachment, MeltedComputer.jpg, which I will attempt to attach 
after submitting this report.

2. When the "Downloading MeltedComputer.jpg" window appears, 
select "Open", "Automatically remember" and "OK".

3.  Repeat steps one & two, noting that the "Downloading ..." window appears, 
and the "Automatically..." box is still checked.

4.  Goto Tools / Options / Download / "Filetypes" and confirm jpg is on 
the "automatically" list.
Actual Results:  
A window asking 'what to do' with file always opens, even though the "do this 
automatically" box is checked and the file type is listed in the "Automatic" 
list in Tools / Options / Download.

Note also that a blank window or tab is opened which is intended by the web 
designer to hold the graphic.

Expected Results:  
1.  The second and subsequent times a file type on the "automatic" list is 
opened, the download window should not appear and the saved action should be 
executed (i.e. open with ...)

2.  The graphic should appear on the blank page and not be processed as a 
download link at all!  Changing the user agent to IE causes Firefox to behave 
as the page designer expects.

Attachment: MeltedComputer.jpg for use as a test case

In theory, using Firefox to view this attachment will provoke the problem.  If
it doesn't, then I will try to find a PHP based BBS to post an attachment on.

That's fine. I've already gone ahead and closed the bug. Sometimes its hard to
find dupes, we've all been there before.

Anyway, you're cc'ed on bug 236541 and you'll get updates on it as things happen.
