Bug 936092 landed in m-i, however,

After opening the web page in new tab, drag and drop onto the contents area is not working.
Drag and drop a file onto <input type=file> is not working.

I tested with newly created profile.

Reproducible: sometimes

Steps To Reproduce:
1. Open e10s window
2. Open any page in new tab
   ex. about:home, https://developer.mozilla.org/En/Code_snippets
3. Attempt to drag & drop html, jpg, png. xpi file to the content area
4. Attempt to drag & drop a bookmark from Library to the content area

Actual Reslts:
No thing happens. 

Expected Results:
D&D should be performed successfully like non-e10s

* drag & drop a bookmark from Bookmarks toolbar and Sidebar seems OK

Comment 1

[Jonathan Howard]

Clarification;
Step 2 above is two steps - i.e. first open new tab, then visit site.
If you open directly in new tab D&D works.

Alternative steps;
Type in address about:newtab (or any non-remote address)
Type in address about:home in same tab (or visit any remote address)
Try D&D (fails)

This is WFM on linux and Windows, e10s enabled.

Comment 3

[Alice0775 White]

I can still reproduce on ubuntu14.04 and Wndows7 with e10s.

:smang, did you should follow str in comment#0?

Steps To Reproduce:
1. Open e10s window --- (there is about:home tab only)
2. Open any page in new tab --- (enter url and middle+ click reload button etc)
   ex. about:home, https://developer.mozilla.org/En/Code_snippets
3. Attempt to drag & drop html, jpg, png. xpi file to the content area
4. Attempt to drag & drop a bookmark from Library to the content area

[Olli Pettay [:smaug][[e-mail]]]

I assume we're somehow missing to creating the drag session in the child process, but why...

Anyone who can reproduce this, do you see any related warnings in the terminal when using a debug build?

Comment 5

[Olli Pettay [:smaug][[e-mail]]]

And yes, I did follow the STR exactly. No luck reproducing.

100% reproducible for me.
Of course, I tested with newly created profile.

[Olli Pettay [:smaug][[e-mail]]]

Can you dnd text from external program to textarea in e10s-FF when this issue happens?

Yes , I can reproduce.
STR:
  1. Open this page in new tab
  2. D&D from a selected text on wordpad.exe to input/textarea on this page.

Actual Results: 
  Nothing happens.

Comment 10

[Alice0775 White]

I can also reproduce the problem on ubuntu. D&D from selected text on gedit to input/textarea on this page.

Comment 11

[Olli Pettay [:smaug][[e-mail]]]

I've managed to reproduce the issue once on a newly created profile. After restarting the issue was gone. Investigating

Comment 12

[Olli Pettay [:smaug][[e-mail]]]

Attachment: v1

This is similar to the "drop" case.

If there are other issues with e10s+dnd, could you file new bugs, thanks
(well, assuming the patch fixes your issue, not only the one I managed to reproduce).

WordPress developers say DnD still doesn't work on e10s-enabled Firefox 40. Any ideas?
