I tried to find a regression range but mozregression was not able to open any version of Nightly older than one month. Is there a way I can find a regression in this circumstances?

You may need to specify --bits 32 to get a 32-bit build. I don't know when 64-bit builds started but they won't go that far back.

This is on OSX, where we ship doubled-up builds, so that isn't the problem. I think our builds didn't use to start on 10.12 (the new beta version of OSX) until recently.

Maybe :mstange can help.

(though tbh it's not clear this is materially different from bug 1287156 in which case investigating this separately may not be a good use of our time)
Right, I don't think there's anything we should do here until bug 1287156 is resolved.

This is fixed in the latest Sierra Beta (which fixed bug 1287156).
