How to create a shortcut to launch a specific firefox profile on a Mac?

Oh, I'm glad somebody else has already done this and explained how to create an application shortcut for a script. Not only is it tedious to start a different Firefox profile via, but cut'n'paste between the rest of the world wasn't working then. A proper Application Bundle did the trick:

  • Open Script Editor
  • do shell script "/Applications/ -P tmp >/dev/null &"
  • Save as an Application Bundle

  • Now you can drag this thing around and place it e.g. on your Dock.
