Additional information:

$ snap list firefox
Name Version Rev Tracking Publisher Notes
firefox 104.0.2-1 1810 latest/stable/… mozilla✓ -

Actual results:

The crash reporter couldn't do its job due to the snap confinement preventing the use of ptrace. Here is is what's in the journal around the time of the crash:
