#16 on 20160619 Windows Nightly, 6 crashes from single installation. But there are 347 reports with this signature, which worth a bug.

indeed https://crash-stats.mozilla.com/signature/?product=Firefox&version=50.0a1&signature=%60anonymous%20namespace%27%27%3A%3ANameResolver%3A%3Aresolve&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&page=1

Thanks for reporting, but it's really just a large cross section of various versions, and ~200 crashes for a release version is a tiny amount, which seems unlikely to be worth tracking without steps to reproduce.  Do you have steps to reproduce?

No, unfortunately.

The number of crashes actually is far more than that, sorry I didn't explain it clearly but the default search on crash-stats is a week. So if I search for the signature from 2016-01-01 then there are 6299 crashes. And from the graph [1], the number of crashes per day is dozens. I don't know if this is still a relative tiny number...

yes, current ~50 per week is tiny, compared for example to the crash signature ranked #300 for version 47

This probably went away with the frontend rewrite, but that should be verified.

[Emma Mason]

Still an issue in v56 and v57.
