firefox release summary score: 6.07, Tuesday 5.12

[68.0]

• no surprises - we had already seen these rising signatures during the beta cycle:
• AsyncShutdownTimeout |...| EnvironmentAddonBuilder: https://bugzilla.mozilla.org/show_bug.cgi?id=1513855 - 7% of browser crashes
• Plugin-related shutdownhang | mozilla::ipc::GeckoChildProcessHost::WaitUntilConnected: https://bugzilla.mozilla.org/show_bug.cgi?id=1541344 - 4.4% of browser crashes

Mobile

• Crash rate is calculated based on usage hours (the time Firefox is actively used).
• Usage hours will be significantly lower on Fennec than on desktop Firefox, so we can't compare mobile rates to desktop rates.
