Release quality metrics (Tuesdays)

Desktop Stability

Nightly

crash incidence (% of users experiencing a crash): 1.92%

Beta

• Crash in [@ MaybeMutex::ShouldLock]
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1845355
  • 5 crashes for 116.0b7, 1 for 116.0b6, unknown why they started now. Needinfoed Emilio because this originates from style code

Release

crash incidence: 0.64%

• Crash in [@ memset | MaybePoison] due to a CPU bug in memset with some versions of VCRUNTIME140.dll
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1844401
  • TIL: We are crashing in memset from VCRUNTIME140.dll. Even though we ship this Microsoft DLL in the Firefox directory (currently in version 14.29.30139.0), if a system-wide version of the DLL is found in C:\Windows\System32, the system-wide version will be favored at load time. This explains why the DLL version (and code) is not the same for everyone.
