    The script context at this point can only access the following things:

    • Global Values/Functions i.e. window, document, or any of the functions/objects/variables bound to the window object
    • Event object

    Example

    <?xml version="1.0"?>
    <?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
    
    <window
        id="findfile-window"
        title="Find Files"
        orient="horizontal"
        xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
      <script type="text/javascript">
      function myFunction(e){
        /*
