this crash signature is regressing (at least in volume) during the 62 cycle - possibly related to bug 1455357.
so far reports are coming from windows installations only and the crashes are happening predominantly in the content process.

I would be surprised if bug 1455357 indeed сaused this one, though won't be impressed if it makes things worse. The bug looks similar to bug 1463962, which has a testcase. So let's see if solving it will solve this one.

It's a duplicate of the bug 1470838 indeed. Let's close this one and continue work in another one.
