And if it does use Online Certificate Status Protocol, is there a way to disable it, so that it uses CRL instead?

You can disable it:

To disable OCSP in Firefox:

Go to "Tools (or Menu button) -> Options -> Advanced -> Certificates" and uncheck Query OCSP responder servers to confirm the current validity of certificates.
