It is even a bit more complicated - CRL checking can mean two different
things:
1. check manually downloaded and installed CRLs, which is what Firefox
1 and 2 will do if you install one. This is different from
2. download CRLs automatically from the "CRL Distribution Point"

afterwards. Firefox 1 or 2 won't do this for you.
So for a typical user, this
