What should Firefox do with this file?

[ron]

Hello,

Clicking on mp3 file url in firefox. I got the standard dialog box:

----------------------------------------

 What should Firefox do with this file?

[] Open with [application (default)]

[] Save to Disk

[] Do this automatically for files like this from now on.

-----------------------------------------

I picked 'Open with [application (default)]' and 'Do this
automatically for files like this from now on.'

Now when I click on an mp3 file url, the file downloads and is
automatically played.

How can I get the dialog box back so I can 'Save to Disk'.
