Could you elaborate on the differences? As far as I understood it firejail, or rather the Linux features that it depends upon, is far more powerful than FreeBS

  From what I understand, firejail is a "syscall filter". This moves it to the same category as capsicum (https://www.freebsd.org/cgi/man.cgi?capsicum https://www.freebsd.org/cgi/man.cgi?capsicum), but without Capsicum's security model, instead implementing something ad-hoc, probably by using Linux' seccmp. Jails, on the other hand, are not a sandboxing mechanism - they are system-level virtualization, like Linux namespaces, but with a simpler interface. You can use it for sandboxing, but it's not what the mechanism fundamentally is.

    Firejail does more than just syscall filtering.

          Looks like a GUI wrapper around jails, with some seccmp hacks to work around deficiencies in namespaces.
