@Daniel, it looks like there was some changes to the sandboxing of Firefox. I needed to add the following rules to make FF 60 work again:

  # new with FF 60
  capability sys_admin,
  capability sys_chroot,
  capability sys_ptrace,
  owner @{PROC}/@{pid}/{u,g}id_map w,
  owner @{PROC}/@{pid}/setgroups w,

Similar to yours except that "owner" works for the files under /proc. Before adding all those rules, I got many crashes in libxul.so and libmozsandbox.so.
