Description

+++ This bug was initially created as a clone of Bug #1553135 +++

This bug is for crash report bp-10b7d77e-9d56-431f-bb8e-e376d0190521.

Spinning off from the original bug since I still see crashes in the most recent Fenix release,
20190812090043: https://bit.ly/2Zn0vMg

Samsung Galaxy Tab S2 seems to the #2 top crashing device, followed by a few LG devices.

Looks like a shutdown race between async screenshot grab and window destruction.

Dropping to P3 because the volume is pretty low. Perhaps fixing the screenshot OOM bug 1577192 will help?

Closing this one out as WFM since there is miniscule volume and all of it is back on 68.
