Java Script Shell

Jash is a DHTML-based window that gives you command-line JavaScript access to the current browser window. With this console you can quickly debug scripts, manipulate the DOM, view the current page's objects, functions, and variables, trace the execution stack, execute arbitrary Javascript, enter new CSS (in IE, Firefox, Opera, and Safari), and much more.
