Why is Perl CGI :: cookie able to set a cookie in IE, but not in Firefox?

I have some CGI Perl code that I am trying to run in the project web space of a SourceForge account. The code can set the cookie browser only when talking to IE, but the cookie is not set when talking to Firefox. When I test Apache on "localhost", both browsers work fine. It is only at the remote SourceForge URL that Firefox removes.

The search included dozens of almost duplicate questions, but usually people have the exact opposite problem! (Firefox is fine and IE has a problem)

Here is the sub utility that I call to set cookies:

sub setCookie {
    my $name = shift;
    my $value = shift;
    my $expires = shift;
    my $path = shift;
    my $domain = shift;
    if( !defined( $expires ) ) {
        $expires = '+4h';
    }
    if( !defined( $path ) ) {
        $path = '/';
    }
    if( !defined( $domain ) ) {
        $domain = 'steveperkins.sourceforge.net';
    }
    my $cookie = CGI::cookie(
        -name    => $name,
        -value   => $value,
        -domain   => $domain,
        -expies => $expires,
        -path    => $path
    );
    $r->header_out('Set-cookie' => $cookie);
}
