1362078 - Drag files from downloads list (Library) to desktop no longer work in Firefox 53 on Mac

Status: RESOLVED DUPLICATE of bug 1330470

(Firefox :: Shell Integration, defect)

Description

[Billy]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170413192749

Steps to reproduce:

Download a file.
Open the "Downloads" list ("Down arrow" in tool bar) and/or click the "Show all downloads" link.
Drag the downloaded file to the Desktop.



Actual results:

It created some kind of XML based "link" (with the filename "Users/myusername/Downloads/sample-pdf.pdf.fileloc") to the downloaded file.


Expected results:

It should have moved the actual downloaded file to the Desktop.

With Firefox v52 (and previous versions) on Mac, when dragging a file from Firefox's "Download list" to a folder in the file system (eg. "Desktop"), it moved the downloaded file to that location.  It seems to be working as expected with v53 on my Windows computer.

I confirm this behavior on MacOSX (still present in the latest nightly).
Ran a mozregression on it:

Could be this bug:
Bug 1235162 - Crash when dragging objects in OS X (objc_msgSend | CFMessagePortIsValid)
