We removed the shutdown notification from onDestroy back in bug 823285 (see https://bugzilla.mozilla.org/show_bug.cgi?id=823285#c21). The reason is that they were unreliable as OOM kills and force quits did not trigger these shutdown notifications. Because shutdown notifications aren't fired on Android, the shutdown handling code in SessionStore.js is just dead code that we can remove.

Gingerbread still supports "Quit" and add-ons could add it back. Thoughts?

We could go even further and remove the "domwindowclosed" handler, but I kept it in case we ever add functionality to close windows (even though it probably doesn't even work properly as-is). Happy to remove it if you prefer.

Comment on attachment 8366952 [details] [diff] [review] Remove session restore shutdown handling I'm convinced that "shutdown" on Android is a fallacy.
