You can mimic the Windows behaviour simply by changing Safari's download directory to /tmp. To do this, open Safari's General preferences pane and, under Save Downloaded Files To, select Other.... In the dialog that appears, hit Shift-Command-G to bring up the Go to Folder dialog. In this dialog, simply type /tmp, hit OK, then hit Select in the main window.
From this point on, all files for which you select "Open with..." in Firefox will be downloaded to the invisible /tmp directory before being opened. The system clears this directory regularly, so there is no need to worry about manually deleting files you don't want. If you wish to move a file from this directory, you can either enter /tmp in the Finder's Go to Folder" field, or you can command-click in the title bar of an opened file in that directory to see the hierarchy.
[robg adds: Obvious but worth pointing out: if you make this change and then use Safari again, anything you download will also go into /tmp.]
