What is about:config

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

Warning: Changing these values can, in rare circumstances, break Mozilla, 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, you can type "about:config" in the Location Bar. In Thunderbird, you could set your Mail Start page in the Options to "chrome://global/content/config.xul" (but you can't until Bug 262626 is fixed).
