1140642 - Image Download via Drag&Drop has the wrong filename

Status: RESOLVED DUPLICATE of bug 291837

(Core :: DOM: Copy & Paste and Drag & Drop, defect)

Description

[alex]

User Agent: Mozilla/5.0 (Windows NT 6.3; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20141126041045

Steps to reproduce:

- Visit an url, which points to an image, but without filename, i.e. "http://foo/32/"

- Open it in a new tab, save the image with Ctrl+s or right click the link and select "save as"
- Image has the name image_32.png (from content-disposition header)
(correct)

- Drag the link into a folder (tested on linux with dolphin (KDE filemanager))
- The image is stored as "32" without extension and ignoring the content-disposition header.

Hi Alex,

The link you provided does not work. This message appears: "not found" on the page. Can you please provide a working link on where I could test this? 

Also, can you please try to reproduce this on the latest release(43.0.1) and latest Nightly(46.0a1) and provide the results? When doing this, you could create a new clean Firefox profile, or test in safe mode, as some of this issues may be caused by third party installed add-ons or custom settings on user's end(https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems).

Thanks,
Paul,

The link is from an internal system, http://foo ist just an example here.

Steps to reproduce the link:
- Start a tiny webserver (i.e. some python stuff)
- Serve an image from /32/
- Make sure it has content-disposition header with a filename

- Then try to save it via ctrl+s (works)
- Then try to drag it into an folder (wrong name)

Header Example:

Request:
  GET /32/
  some-request-headers: here

Response:
  HTTP/1.1 200 OK
  Server: nginx
  Date: Tue, 22 Dec 2015 23:29:06 GMT
  Content-Type: image/png
  Transfer-Encoding: chunked
  Connection: keep-alive
  Content-Disposition: filename=image_32.png

The last header has the filename for ctrl+s, which is ignored on drag&drop.

This is not likely to be a layout problem. But not sure where the code for this lives... networking? Widget?

Drag and drop.  And it's a pretty clear duplicate...
