All the Mozilla Firefox users know the about:config way to access advanced settings in their beloved browser. But this way the settings are not listed category wise but alphabetically which is very confusing for a beginner. Another problem with this method is that there is no description of what a setting can do and what are different possible values. The Configuration Mania add-on solves both of these problems by offering an easy to follow interface where you can access most common advanced settings in a very nice, user friendly and categorized interface.
You can download and install the Configuration Mania add-on in Mozilla Firefox browser like you usually do from its web page. After the installation of this add-on you would see a new item in the menubar labeled Configuration Mania. If you have enabled to view menubar, then it is located under the Tools menu.
Most of these settings cannot be accessed otherwise in such an easy to use manner. Using these settings you can tweak Firefox to your own taste and make it perform a tad bit differently than the average Joe. So if you want to tinker with the advanced Firefox settings through a graphical user interface, then try the Configuration Mania add-on.
