1206765 - Drag&drop to FF returns "Firefox can't find the server at <weird/unknown URL>"

Status: UNCONFIRMED

(Core :: DOM: Copy & Paste and Drag & Drop, defect, P5)

Description

[PeterJ]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0
Build ID: 20150914185908

Steps to reproduce:

I run FF/linux64

Name: Firefox
	Version: 41.0b9  (not really, IIUC ... )
	Build ID: 20150914185908
	Update Channel: release
	User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:41.0) Gecko/20100101 Firefox/41.0
	Multiprocess Windows: 0/1 (default: false)

When I drag-n-drop should-be-browser-openable files (media, html, etc) from Desktop into open FF window, instead of displaying the content of the file, I get 

  "Firefox can't find the server at <weird/unknown URL>"

Opening the same files via the File-> menu, there's no problem viewing them.

For example, 

DL http://www.w3schools.com/html/mov_bbb.mp4 to Desktop,

	(1) Open Firefox
	(2) *DRAG* Video file (file:///home/pj/Desktop/mov_bbb.mp4) into open FF's main window
		==>
		"Firefox can't find the server at www.楦敬⼺⼯潨敭戯慬敫獲䐯獥瑫灯洯癯扟扢洮㑰਍.com."
	(3) create "Hello World" file:///home/pj/Desktop/test.html
	(4) open file (file:///home/pj/Desktop/test.html) in FF
		==>
		"Hello World"
	(5) close tab
	(6) open new tab
	(2) *DRAG* test file (file:///home/pj/Desktop/test.html) into open FF's main window
		==>
		"Firefox can't find the server at www.xn--48b157p22ohqxjtbyze8sbk7meam792i87ih5jmvd34oba1t49j94aub.com"

Works fine for me on Linux.

Bulk-downgrade of unassigned, 4 years untouched DOM/Storage bugs' priority.

If you have reason to believe this is wrong (especially for the severity), please write a comment and ni :jstutte.
