Disable it?
It's a new feature in NSS.  New NSS features are almost never enabled by
default.  That policy is required for backwards binary compatibility.

Firefox must enable it.  It doesn't take much software to do so, but it
must be done and Firefox hasn't done it yet.

Actually, I think it tries them in reverse order.  Not sure.
It tries them until it finds a CRL that is a full CRL, not a partial CRL.
It determines this by the presence or absence of a critical IDP extension
in the fetched CRL.  Any CRL with a critical IDP extension is treated as
a partial (a.k.a "partitioned") or indirect or delta CRL, which are not
supported by NSS, and are ignored.
