Original GitHub issue: https://github.com/netblue30/firejail/issues/2930

The firejail man page reads:
--seccomp
... a system call can be specified by its number instead of name with prefix $...

However, 0.9.56.2-LTS and later do not accept dollar sign in arguments to seccomp-related parameters (tested on Ubuntu 16.04.6 LTS).
The problem seems to be introduced in
commit 322ce2c Nov 6, 2016 "seccomp rework"
Proposed fix is in pull request #2929
