Right now fennec sends a event when ui / delayed ui is ready. This is inconsistent to fennec closing a window. There fennec use observers. Since there are already used observers for ui ready / delayed ui ready we should use those. "final-ui-startup" "browser-delayed-startup-finished"
(In reply to comment #0) > "final-ui-startup" This is fired by the platform, not the front-end. See: http://mxr.mozilla.org/mozilla-central/source/toolkit/xre/nsAppRunner.cpp#3645 > "browser-delayed-startup-finished" I would want to keep our existing UIReady and UIReadyDelayed events. Events are nicer for the front-end JS (fennec and add-ons). But we can add the new notification as well.
I don't see a need to make this change. Please re-open if you still want this.
