This happens only if the content-type is guessed or if the server sends a content-disposition:attachment header.
Can you please provide a link to a file where you get this behavior ?

It has been happening for a long time (and I was in a foul mood so I decided to file a bug).
I don't have a URL, but the latest occurrence was when I clicked on the attachment-indicator in Thunderbird.

You get this behavior if a page sent a content-disposition:attachment header along with the file.
That header always forces a save as dialog regardless if you have a saved decision for the given file type.
