Comment 10 for bug 90378

I agree with Randall that this behaviour is quite annoying.
We also run a web application that allows us to download on-the-fly-generated OpenOffice documents, for instance packing-list documents.
A user downloads a packing-list just for printing, not for keeping the document. But sometimes, before printing, it is useful to edit the document to add some manual data. So what happens now with hardy is, the user needs to save the document, then edit, then print.
Is there any way for me to set the permissions with which firefox saves downloaded files?
