How To Set Up An SSL Vhost Under Apache2 On Ubuntu 9.10/Debian Lenny - Page 3
7 Configure Firefox To Trust CAcert.org (Optional)
If you use a CAcert.org certificate, your browser most likely doesn't trust this certificate and will show a warning. This chapter explains how you can import the CAcert.org root certificate into Firefox so that it won't show this warning anymore (please read http://wiki.cacert.org/BrowserClients for other browsers like MSIE, Safari or Opera).
Please note that if you run an e-commerce web site, you should better buy a certificate from a trusted CA because you can't ask all your visitors to reconfigure their browsers.
Please visit http://www.cacert.org/index.php?id=3 and click on the Root Certificate (PEM Format) link (http://www.cacert.org/certs/root.crt):
The Downloading Certificate dialogue opens. Click on View to examine the certificate:
Please make sure that the fingerprints are as follows:

MD5 Fingerprint: A6:1B:37:5E:39:0D:9C:36:54:EE:BD:20:31:46:1F:6B
Click on Close afterwards:
Next check Trust this CA to identify web sites. and click on OK:
Now go to Tools > Options...
