Thank you for your reply!

I don't care about launching them, I just want to save them automatically.

Is there something in about:config I can change to re-enable it, then?

Using Command Prompt

1. Open Command Prompt by typing "cmd" or "command" in RUN dialog box.

1. Now provide following command:

assoc .exe=exefile

Thank you for trying to help, but this is unrelated to the question I'm asking.

My Windows associations are fine, I just want Firefox to automatically save the files instead of prompting every time.

Thank you!

This helped me find the file I needed to edit to get what I wanted.

For anyone finding this thread in future, you need to add the following object to the mimetypes section:

   "application/x-msdos-program": {
     "action": 0,
     "ask": false,
     "extensions": [
       "exe"
     ]
   }
