Firebug has built-in command line API and one of the built-in
functions is $
see: http://getfirebug.com/wiki/index.php/Command_Line_API#.24.28id.29
The function expect element ID e.g: $('nav')
If you include jQuery in your page, the $ function from jQuery is used
instead.
But jQuery expects a CSS selector e.g.: $('#nav')
In your case, jQuery is probably not included so, you need to use $
('nav')
or make sure to properly include it.
