.14] Crash in shutdownhang | libsystem _kernel .dylib@0x41b2
This bug was filed from the Socorro interface and is report bp-4a926cda-39ea-4655-8dbe-175dd0181025. ============================================================= These shutdown hangs are 10.14 specific: https://bit.ly/2Q4F6P9. They are occurring with various versions of Firefox. They also affect 10.14.1. There are some mentions in the comments of crashing when quitting. Filing since we should watch this as 10.14 rolls out. Some other Comments: *Firefox is not responding, not even in safe mode *Keeps crashing especially with the new MacOs Mojave *I have consistently had problems with AOL locking up for the past several months. The situation has gotten worse since I upgraded to MacOS Mojave. AOL now locks up at least once during each session. The only resolution that works is to Force Quit AOL and start over. At times, I have to restart my computer to regain access to AOL.

Given the stack this feels like a QuotaManager issue. The shutdown procedure for QuotaManager bounces a runnable from main thread to its background thread and back, all the while spinning an event loop waiting for the runnable to get back, which it apparently doesn't, since that's where it's hanging waiting for an event.
Component: General → DOM: Quota Manager
Setting to P3 till we find someone to work on it.
