It looks like something about gfx/layer.

Based on recent data it does not look like this is affecting current Firefox versions but is affecting current Thunderbird versions.

Product:
74% Thunderbird vs 26% Firefox

Firefox Versions (current versions appear unaffected):
33% Firefox 39.0
22% Firefox 38.0
11% Firefox 37.0
11% Firefox 44.0
11% Firefox 47.0
11% Firefox 48.0

Thunderbird Versions:
81% Thunderbird 45.*
19% Thunderbird 35.*

Looking at the stacks it appears this is a very different issue with Thunderbird than it is in Firefox. Since there are no reports in current Firefox versions I'm inclined to call this RESOLVED INCOMPLETE (unless someone can reproduce this in a current version). The Thunderbird crashes probably deserve their own bug report.

As an example:
bp-bdda6a7a-c8a4-4521-96d9-aaf262160712 (Firefox) vs bp-87c39664-d6ef-442a-adfb-5f4922160926 (Thunderbird)

The crashing thread stacks are the same but thread-0 is drastically different. Firefox seems to come from Graphics [mozilla::layers::CompositorBridgeParent::ShutDown] while Thunderbird seems to come from Networking [nsSyncStreamListener::WaitForData()].

I agree. (Although at this time not worth opening a thunderbird bug report - unless a user has a reproducible case)
