Ouch. It seems that this is broken and the version of MozRepl::RemoteObject that fixes this is not yet released on CPAN. The workaround fix is likely adding these lines at the start of your script until you can upgrade to v0.32 of MozRepl::RemoteObject:

use MozRepl::RemoteObject;
BEGIN {
    if( ! *MozRepl::RemoteObject::Methods::dive{ CODE } ) {
        *MozRepl::RemoteObject::Methods::dive = \&MozRepl::RemoteObjec
+t::__dive;
    };
};
use WWW::Mechanize::Firefox;
