I need to call an executable script that I wrote when I click on a link to a file of a certain file type. I used to be able to browse to my script in order to set it as the desired application, but now I can't find any way to persuade Firefox to call my script when, for example, the linked-to file's name ends in '.dng'. Where is the list of such applications, and how do I add my script to it?
