Firebug : Problem with jQuery in WordPress admin panel

Question

I'm trying to make my first plugin and I have a problem with firebug. When I use firebug console in WP Admin Panel doesn´t work correctly. For example when I use the selector $('#wpbody') the console return null value. The WP panel include jQuery library and I don´t know why firebug works wrong.

Any advice or sugestion?

Tested with WP 3.1.3 and 3.2.1

Thanks, Marcos.

WordPress uses jQuery in noConflict() mode, so $ is not available for use in Firebug console. Just use jQuery('#wpbody') instead.
