This is a fatal assertion:
FATAL ERROR: AsyncShutdown timeout in profile-before-change Conditions: [{"name":"SessionFile: Finish writing Session Restore data

I think session store is timing out, probably due to TSan being slow or something.

Blocks: tsan
Group: core-security
Component: Memory Allocator → DOM: Navigation
Flags: needinfo?(a.beingessner)

We have quite a few intermittents related to tsan taking too long, is there a reason you wanted me to look more closely at this one in particular? I don't see anything particularly strange going on.

Flags: needinfo?(a.beingessner) → needinfo?(continuation)

I just wanted you to keep an eye on it in case it becomes frequent. But it looks rare so far.

Flags: needinfo?(continuation)

Ah ok, yeah. I try to keep an eye on all the tsan intermittents that hit my inbox, so CCing me is sufficient for that.

P3

move to Session Restore component

Severity: -- → S3
Component: DOM: Navigation → Session Restore
Priority: -- → P3
Product: Core → Firefox

Haven't seen this in a month so closing until it shows up again.
