Is consistency overrated?

I have a Firefox extension: https://addons.mozilla.org/en-us/firefox/addon/lightweight-theme-switcher/  I've been playing with adding a new menu, and was struggling to find all the default menu names.  Here they are: file-menu, edit-menu, view-menu, history-menu, bookmarksMenu, tools-menu, windowMenu, helpMenu.  Am I the only one that this bugs?
