Does Chrome check CRLs?
As a secondary function they can also contain some number of non-emergency revocations. These latter revocations are obtained by crawling CRLs published by CAs. Online (i.e. OCSP and CRL) checks are not, generally, performed by Chrome. The CRLs from that set go to make up the published CRLSet.
What is OCSP used for?
OCSP is used to check the revocation status of X509 certificates. OCSP provides revocation status on certificates in real time and is useful in time-sensitive situations such as bank transactions and stock trades.
Does Firefox use OCSP?
Firefox currently relies on traditional OCSP when a certificate is delivered without a stapled OCSP response. By default, Firefox ignores the revocation check (i.e. soft-fails) if a valid response is not received from the OCSP server within 2 seconds (10 seconds for an EV certificate).
