Created attachment 438332 [details] [diff] [review] patch From parent bug: nsIWindowMediator tracks windows until they are destroyed, but there's a brief period when windows are closed without being destroyed yet. Session restore should only care for windows that are open and should thus skip windows that aren't. I don't think this is relevant for real users, but it likely is relevant for tests and could in fact be the cause for some intermittent failures we're seeing. I ran test on my Fedora 12, no failed test seen.
