Hi, Here is a crash-stats search that shows all the crash reports in the past 7 days that have a "MozCrashReason" field -- which means they were triggered by MOZ_CRASH or MOZ_RELEASE_ASSERT -- faceted (i.e. aggregated) by that field:
https://crash-stats.mozilla.com/search/?product=Firefox&_facets=moz_crash_reason&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=moz_crash_reason#facet-moz_crash_reason I've included the output below. (Apologies if it gets munged when the email is processed; just click on the link above to see the live list.) #1 by a long way is shutdown hangs. No great surprise. #2 is unannotated MOZ_CRASH() calls, i.e. there is no string argument given. These are mostly OOMs, though there are a few others in there. These ones should be annotated so they show up separately. >From #3 down we have smaller numbers, but many of them are still non-trivial, and a lot of them are probably indicative of problems that are very easy to fix if the right person sees them. Please take a look through the list to see if any of them are familiar to you. (If you're wondering why I made this search... I've found that many crash reports lack enough data to be actionable -- especially those involving crashes caused by bad memory accesses. So it's worth focusing to some degree on the crash reports that are more likely to be actionable, and places where we deliberately abort are an obvious case.)
