Of course, but as you have already said, if the connection is
abandoned (someone just switches off their PC), this record will
remain in the database.

You will need to create some mechanism, perhaps a keep-alive update of
the record could be sent from your application every 10 minutes. Your
connection counter can remove connection records if they are more than
20 minutes old.

But Firebird does not have this ability natively. There is no need for
the database engine because the Firebird licensing allows unlimited
connections. If you want to introduce limitations for your application
licensing, you need to create tables and insert / update / delete
information yourself.
