(In reply to Henrik Skupin (:whimboo) from comment #1) > So whether we missed to monkey patch mozcrash in this case, or there was a > real crash of Firefox. The former is the problem here and it will be fixed with my patch on bug 1223277.
Depends on: 1223277
The underlying issue here should be bug 1376795.
Depends on: 1376795
The landed workaround didn't seem to help for this test. So we have to wait until we are clear about the real underlying issue.
is there any work being done to get to the bottom of this?

So all the last days these failure seem to happen nearly exclusively for headless mode. There are only rare situations for Mn jobs. I tried to reproduce it locally but wasn't successful at all. Maybe it's specific 10.10 related? I have 10.12 installed. I will pick one of the affected builds. Maybe it will help to get it reproduced.

I cannot reproduce it locally whatever I try to do. So I'm figuring out now how to use MacOS one click loaners, if possible yet.

This hang might actually be related to bug 1433873 because we hang after the restart. The OS X failures will be gone soon.

Looks like no more failures of this test on Windows since mid of July. As such I would say we just mark this bug as WFM given that I don't know what could have fixed it.
