By querying Nightly crashes reported within the last 2 months, here are some insights about the signature:

  • First crash report: 2023-12-04
  • Process type: Multiple distinct types
  • Is startup crash: No
  • Has user comments: No
  • Is null crash: No

All the crashes are coming from a single user, this is likely invalid

FWIW, let's not leave it in the General triage list.

Component: General → Layout
Component: Layout → CSS Parsing and Computation

Yeah this is probably bad memory.
