## Summary:

  Usage:

  Start the REPL:

  M-x firefox-javascript-repl RET

  To stop the REPL, kill the *firefox-javascript-debugger* buffer:

  C-x k RET yes RET

  or quit Firefox from within Firefox.

  Description:

  REPL into a new Firefox instance's JavaScript engine.  A new
  throwaway Firefox profile directory is created before each run, so
  you won't need to modify your existing profiles.  This mode takes
  care of starting the new Firefox process in debugging mode, which
  may be tedious to do by hand.

  This `comint' mode is barebones and unstructured, meant for quick
  JavaScript experiments.  On newer versions of Emacs with
  `comint-indirect-buffer' support, syntax highlighting happens on
  the current statement.

  Paste each statement from `example.js' into the REPL to try it out.
