This is a deep, interesting stack.

  • nsAppStartup::Quit is notifiying quit-application-granted
  • Some observer of quit-application-granted (aka ShutdownPhase::AppShutdownConfirmed) (yet to be identified) is doing a nsThreadPool::ShutdownWithTimeout that spins an event loop, waiting for a pool
  • While in that loop, we get a CanonicalBrowsingContext::ChangeRemoteness event that will ask for a nsFrameLoader::EnsureRemoteBrowser that will make ContentParent::GetNewOrUsedLaunchingBrowserProcess fail

So we actually started parent shutdown and apparently we already notified ShutdownPhase::AppShutdown while on top of the nested event loop, which caused our child processes to start shutdown. Several things come to my mind:

  1. We might want to check the path that starts from CanonicalBrowsingContext::ChangeRemoteness if we miss some shutdown check.
  2. We probably want to find the cause for nsThreadPool::ShutdownWithTimeout during quit-application-granted and avoid it (moving it probably to the next phase). To help diagnose the cause, we could add the pool's name to the SpinEventLoopUntil annotation inside nsThreadPool::ShutdownWithTimeout (which would be nice to have in any case, I'd say).
