Seeing these crashes on nightly with MOZ_CRASH(IPC message size is too large).

Comment 1

[Jan Varga [:janv]]

Hm, this is weird. localStorage is limited by 5MB total usage per origin, loading of all keys shouldn't create such big IPC messages.

Comment 2

[Jens Stutte [:jstutte]]

This happened only on a very small range of nightly builds (20200913213803 - 20200917100940). If it does not re-appear, I think we can ignore it? Or are there other similar signatures we are overlooking?

Closing because no crashes reported for 12 weeks.
