Here's a little script to get Chickenfoot to add some keyboard shortcuts to firefox.

Add this to run as a trigger on window open and you'll be able to acquire focus on the current chickenfoot editor window by pressing 'alt-C' and to regain focus on the main tab (which is something I've often wanted to be able to do) with 'alt-D'

// attach keyboard shortcut (Alt-C)
chromeWindow.addEventListener("keypress",
   function(event) {
     if (event.altKey && event.charCode == 'c'.charCodeAt(0)) {
       event.preventDefault();
       var sidebar = Chickenfoot.getSidebarWindow(chromeWindow);
       if (sidebar) {
          sidebar.getSelectedBuffer().focus();
       }
     }
    },
    true);


// attach keyboard shortcut (Alt-D)
chromeWindow.addEventListener("keypress",
   function(event) {
     if (event.altKey && event.charCode == 'd'.charCodeAt(0)) {
       event.preventDefault();
	   tab.focus();
       }
    },
    false);
