Create certs uses always the same serial number and this leads to some errors when you recreate new certs before the old ones expire. Firefox will blocks the connection with the new certs as the old one is still in the cert store and both have the same serial number.
Workaround:
manually delete the old certs from the firefox cert store
or create the certs the manual ways as openssl uses for each cert a different serial number
Probably this issue exists also in other browser, but I havn't test it.
