In Internet Explorer and Firefox there is no "inner" way to check the SHA256 fingerprints at this time (Nov. 2011.). You can do it by following the instructions below.
Install openssl package:
1. Install openssl package or use Windows openssl installer
Linux: OS generaly contains openssl or it can be install very easily with package installer. Windows: OS doesn't contain openssl so you will have to download an openssl installer.
Download the Windows installer:
http://www.slproweb.com/products/Win32OpenSSL.html
last recommended link "Win32 OpenSSL" and full "Visual C++ 2008 Redistributables" packages.
2. During the installation use these commands
Replace <certificate name with path> with the downloaded CA certificate's path.
If the certificate has Base64 PEM format, then leave this from the command line: "-inform DER"
openssl x509 -noout -fingerprint -md5 -inform DER -in <certificate name with path>
openssl x509 -noout -fingerprint -sha1 -inform DER -in <certificate name with path>
openssl x509 -noout -fingerprint -sha256 -inform DER -in <certificate name with path>
