The Applications panel has limited functionality for editing. You can change the action for an existing file type but you cannot add or remove file types. Entries are added automatically when you download files and select actions for them. See Adding download actions.

If you are having problems or if you just want to start fresh, you can reset all download actions to the default settings. Open your Firefox profile folder, delete (or rename) the handlers.json file and then restart Firefox.
