Looking at the code, this test is waiting for a notification to not be dismissed before continuing. It looks like PopupNotifications.jsm does set "dismissed" to false before populating the notification, but I don't see any yields or anything that could allow for dismissed to be false while the notification is still unpopulated (assuming run-to-completion semantics). Maybe I'm missing something. Anyway, if we have the test wait until the notification is populated as well as not dismissed, it should stop failing.

Comment on attachment 773692 [details] [diff] [review] test fix I'm skeptical that this will help, but it certainly won't hurt.

Thanks - we'll see how it goes. https://hg.mozilla.org/integration/mozilla-inbound/rev/dc6fc156140e

Huh, this appears to have fixed it. I'm still a bit puzzled about how this situation could happen.
