Browser plugin not showing data [#1865916]

I installed the browser plug in and module in drupal. On this (development environment) I gave authenticated users access to the 'Access Firebug Debug' permission. Site Admin has access to that and 'Execute Firebug PHP'.

Browser/Client

Firefox 17.0.1
Ubuntu 11.10
Firebug 1.11.0
DrupalForFirebug 2.0
Logged in as User 1

Server (development box)

Drupal 6.25
Redhat 5.8
PHP 5.3.3

In the source code of my page, I can now see

's with class names such as drupalforfirebug_general and drupalforfirebug_sql. Such as:

<div id="drupalforfirebug_general" style="display: none">
<fieldset>
<legend>Drupal for Firebug General Messages</legend>
There were no messages sent to the general log. Please use "firep($item, $optional_title)" to output messages to this console.</fieldset>
</div>

So it appears that information is binging handed to the browser from Drupal.
