When you say "the" self-signed cert, which do you mean? For the
procedure you show, only your (private) CA cert is selfsigned,
the server=EE cert is NOT selfsigned. (It is signed by a key
belonging to the same owner=you, but not *its own key*.)

If you used the same DN, including CN=*.parisgeo.cnrs.fr, for both
the CA and the server=EE, it won't work, and it looks like you did.

<snip rest>
s_client thinks the issuer and subject names are identical.
If you want the server=EE cert signed/issued under a CA cert,
the server=EE name (subject) and the CA name (issuer) must be
different. I prefer to make CN different, because that's what
people mostly look at, but it's sufficient to make any field
in DN different e.g. Org or OrgUnit.

OpenSSL signs correctly; assuming the certs weren't damaged,
this probably means Firefox tried to verify using the EE key
rather than the CA key because the name is ambiguous.

Don't use the same name for the CA and the server.
