Yes. I face this bug reraly on a new profile.

Sorry, I don't remember the concrete date about which Nightly starts to happen......
I feel that I faced this bug frequently from 11/20 (Fri) ~ 23 (Mon). At least I seem at that time which U.S entered to thanksgiving holiday.

Additional Information are:
* WIth [yeasterday's Nightly](https://hg.mozilla.org/mozilla-central/rev/abafe6c923eb566ffb94fd6afe0e06766d0c27a6), I have not faced this bug. But I'm not sure about that this bug has been fixed actually. This bug sometimes does not happen. I seem that the step to reproduce is depends on some timing issue.
