@kellerd Unfortunately yes, it does crash that particular flavor of Firefox. Hopefully Mozilla can fix that issue, as it works fine in standard (non-ESR) versions (v56.0.2 and most versions before that, both 32-bit and 64-bit, are ok).

Closing as there isn't much to do, and you've already done quite a bit of Firefox regression testing.
