This is probably fixed by bug 1506311 --- for a couple days web replay would break during startup on 10.13.

All the 10.13 crashes in this signature stopped, but there is one 10.14 signature from 20181114100226 which I think is after the patch landed.

Since my last comment, I see one crash on nightly, Build 20181120100045. MOZ_CRASH(ChildProcessInfo::LaunchSubprocess).

Comment 4

[Marcia Knous [:marcia]]

One 10.13 crash in this signature in the 20181228093007 build on nightly 66, but none since then. Will add the appropriate tracking flag.

No recent crashes, closing this one out as WFM.
