[Ralph Giles (:rillian)]

From the crash reports, this isn't just a macOS issue, but it's all confined to 52 and earlier. If it's easy to reproduce we could bisect to find a fix, but realistically we'll probably just wait for Firefox 60 esr to address this.

Closing because no crashes reported for 12 weeks.
