This is a Cocoa Widgets bug. Or at least some of these crashes are.

Bug 1577886 landed support for `mac_crash_info` data in Mozilla crash reports. Now one has appeared with this bug's signature and very interesting `mac_crash_info` data:

        {
          "num_records": 1,
          "records": [
            {
              "message": "Calling windowShouldClose: on the delegate for the ToolbarWindow 0x115acc800",
              "module": "/System/Library/Frameworks/AppKit.framework/Versions/C/AppKit"
            }
          ]
        }

I haven't investigated, but I suspect this "message" is written just before the call that hangs. It would normally be zeroed out again if that call succeeds. But in this case it didn't.

Edit: This is exactly what happens.
