Configuration Mania is a Firefox add-on that organizes and displays many of the options that are normally only available through about:config. Here are just a few o the things you can change using Configuration Mania:
- Location bar auto-complete behavior
- Default domain guessing behavior (should Firefox add www or .com when you type a word into the location bar?)
- Tab behavior (where to display the close button, default tab width, etc)
- Hide the Go button next to location bar
- Change your user agent
- Adjust cache settings
