Seems like a similar issue to bug 1185099. It failed to access `event` variable. such case could happen if the code relies on global `event` variable in event handler.
Let's triage it in FF for Android for now. Retriage in TE Mobile if need be.
Tested on 47, 48.0b9 and Nightly 50.0a1 on Huawei Nexus 6P (Adroid version 7.0). The issue is reproducible following the STR from the description. Also please note that the issue is reproducible on Firefox for desktop 47.0 on Windows 10. See issue: https://bugzilla.mozilla.org/show_bug.cgi?id=1287713.
