Double-clicking or opening (contextual menu -> open) on a "forwarded" mail attached to a message in the Mozilla Mail application opens a new navigator window instead of a message window. This bug prevents the user to correctly print or display a forwarded mail. It also prevents users to re-forward a forwarded mail without forwarding the whole messages. It's an even bigger problem when dealing with signed or crypted mails. This problem as been verified using Linux, or MacOSX Reproducible: Always Steps to Reproduce: 1. Forward a mail to yourself 2. open the new mail 3. open the forwarded mail in attachment Actual Results: open a navigator window and display the (raw ?) message (I mean : not in a very convivial way). Expected Results: open a message window displaying the forwarded mail and its attachments, certificates, signatures... allowing the user to forward, reply, print, save .... the mail.
