Comment 13 for bug 1088260

I caught it right in the action. Apperently, the "open file" dialog in firefox defaults to a directory in the file manager called /home/user-name/desktop. What happens is this directory doesn't exist inside files in the first place, so it makes a folder automatically - the "desktop" folder. Once you upload a file to a web dialog, it then stays in the directory if which the file was uploaded from, so obviously it won't happen in the same dialog again. I hope the image and the info helps.
