Firefox-dev.app is an AppleScript launcher that opens Firefox with the -P Development argument.

Instead of having Firefox prompt me for which profile to load each time (default or Development), Firefox.app will use the default profile and Firefox-dev.app will specify the Development profile.

Saves: a double-click.
