mcomella had mentioned the idea of enabling strict mode in Nightly here, but that's probably a bit too extreme.

For now, if someone picks this up, please consider alternative ways of getting more information about this crash - e.g., logging strict mode warnings to Sentry, or (if viable? - would need to check with RelMan) creating a build that rolls out to a very limited percentage of installations (e.g., distribute it to 1-3% of nightly users).

So, to clarify: the priority for this bug current represents the task of "getting more information" - we likely don't have any actionable fix ready to be worked on right away.
