Related to other add-ons

  1. about:me
  2. about:tabs

Miscellaneous errors that are seemingly useless

  1. about:certerror

These windows can be closed using Ctrl (or Cmd)-w. Note that some about: menu options may not show up in applications that do not support them.

ViewAbout started initially from a need to view about:crashes on Thunderbird.
