about:config is a special location that lists all application preferences (read from "prefs.js" and "user.js"), many of which are not present in Options/Preferences dialog. Preferences can also be changed here.

Warning: Changing these values can, in rare circumstances, break Mozilla Suite, Firefox, or Thunderbird or cause strange behavior. Only edit these preferences if you know what you are doing.

Opening about:config

In Firefox and Mozilla Suite, you can type "about:config" in the Location Bar.

In Thunderbird, use AboutConfig extension. (See also Bug 262626.)

There's a version of AboutConfig extension compatible with Nvu here.
