I've tried for several hours without success, using what is in the 
documentation ( 
https://developer.mozilla.org/en-US/docs/DragDrop/Recommended_Drag_Types#Dragging_files_to_an_operating_system_folder 
)

I've pasted the code here : http://pastebin.com/jw30ggtw

I used Components.utils.reportError for tracing, since console.log 
didn't work in this case.

What I can see :
The dataProvider contructor is called, but the getFlavorData() method is 
never called.
The drag works anyway on windows, but not at all on OSX.

I'm really stuck now, and can't see what I am missing.

Any advice would be greatly appreciated.


Thank you

PS: we try to mimic chrome DownloadURL feature :
