It seems unlikely, there are similar extremely-low-volume crashes in 66 already: https://crash-stats.mozilla.com/report/index/6dd1bd93-0094-4dee-8a1c-9760f0190418

This crash looks curious though. This had an URL but it's inaccessible for me...

Comment 2

[Julien Cristau [:jcristau]]

Seems this isn't new and we don't know what caused it after all...

Comment 3

[Emilio Cobos Álvarez (:emilio)]

This doesn't seem to have crashed ever again? This is not very actionable as-is.

Comment 4

[Marcela (Please NI request to Brindusa Tot)]

Closing this as resolved- worksforme, there were no crashes with this signature in the last 6 months.

Comment 5

[Marcela (Please NI request to Brindusa Tot)]

Reopening this issue because it seems that for the Signature
@ PLDHashTable::Add | nsAtomTable::Atomize there are still crashes occurring in the last 6 months

[BugBot [:suhaib / :marco/ :calixte]]

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
