Install MozRepl Extension for Firefox

Before it is ready to run the javascript codes in Emacs, an extension of MozRepl for firefox is required. The MozRepl extension is an agent listening the request from Emacs. After the installation, start it from the Tools -> MozRepl -> Start. Now you can run the javascript from within Emacs.
