Firefox - Configuration Mania Extension

The Configuration Mania extension allows you to tweak several of the preferences that are not available via the standard Preferences screen. Given the incredible flexibility of
Firefox, this tool really comes in handy when you need to change the low-level settings to improve performance, usability, or navigation, or for development purposes. Each section has
several options, which are categorized by the following:
* Browser
* HTTP Network
* Chrome Uninstaller
* Mouse Wheel
* Keyboard Navigation
* Master Password
* Debug

This extension is a good way to get around having to find preference names and values to tweak your browser and can be used to get your feet wet with hacking Firefox preferences and
tweaking hidden settings.
