crashes with this signature on windows are somewhat spiking up since firefox 57 - looking related to bug 1378070?

Any ideas, Alex?

[Karl Tomlinson (:karlt)]

Bug 1429666 may have been a big cause here.
If so, bug 1423901 may explain fewer crashes on 59 (none so far).

[Liz Henry (:lizzard) (relman/hg->git project)]

Since I don't think we've ever seen crashes in 59 with these signatures I'm marking this unaffected and thus dropping it from triage. We can either close it WORKSFORME now or after 59 release.
