First FIrefox CRASH in a long time. Ony had one tab/link open, did an upgrade to 118b7 from 118b6, and it crashed upon restart.

Actually, let's dupe this since bug 1315306 and its related bugs have all our attempts to track this down over the years. We've had no luck explaining this beyond "the amount of Telemetry I/O performed at shutdown sometimes takes longer than the shutdown watchdog would like".

Maybe if we're lucky the reduction in ping size from bug 1852098 or the eventual deprecation and removal of the legacy Telemetry "event" ping will reduce the complexity and volume of at-shutdown I/O sufficiently to make this bearable.
