Mozilla has documentation on Firefox's Chrome URLs, but the list is rather incomplete. I found another article on the same topic, but unfortunately, the information is terribly out-of-date (Firefox 1.0). The first article does give instructions for finding Chrome URLs, but before I spend time making my own list, I am wondering if a more complete list already exists.
I could not find a better list, so after diggin through Firefox's various dialogs and windows, I present the following... Relevant as of Firefox 10.
