A steady crash for version 60, in the top 75, and continuing in version 68

But virtually zero visibility in betas and nightly, with an average of only one crash per month in betas - so I'm going to assume this crash still exists in 70 and 71.

crash rate unchanged from version 60

Similar ranking for version 78.2.1

No idea why we'd crash.

Same ranking for Version 91.2.1 and version 78.14.0 ~#102

So it doesn't seem to have been helped by bug 1175168

Anje, have you had any crashes in the past half year? If yes, what are their crash IDs?

Anje, have you had any crashes in the past half year? If yes, what are their crash IDs?

No. So far all is good - Not had any crashes. If I do then I'll post here.

Still plenty of version 102 crashes https://crash-stats.mozilla.org/signature/?signature=PL_strncpy%20%7C%20PL_strncat%20%7C%20nsParseMailMessageState%3A%3AGetAggregateHeader&date=%3E%3D2022-07-29T18%3A38%3A00.000Z&date=%3C2023-01-29T18%3A38%3A00.000Z&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&_columns=startup_crash&_sort=-date&page=1#summary
