Since the "Upload a file" file selector doesn't work in Firefox, can you make a note in, maybe the 'Formatting help' text about being able to drag and drop images? D&D actually seems to work.
It half works; you have to do it twice for a file and the file will be uploaded when you hit "Post reply". Sucks for multiple files, though. If I'm attaching more than one image, I put one in the first edit, then do another in a subsequent edit and so on.
