Problem Description
The recently released version 3 of Mozilla Firefox can cause trouble when trying to access encrypted web-sites such as our software pages. When accessing the encrypted page for the first time, Firefox 3 could show an alert message "www.cebitec.uni-bielefeld.de:443 uses an invalid security certificate".
The reason for this is that we are using a certificate that is not issued by an officially recognized Certification Authority (CA). Certificates are used to identify the provider of a secure web-site. Instead of purchasing such a certificate from a commercial CA accepted by Mozilla, we use a so called 'self-signed' certificate. We do not intend to purchase such a commercial certificate, however, Firefox 3 is now much more restrictive when it comes to unrecognized CAs (we could get a certificate from the Deutsche Forschungs-Netz (DFN), but this is also not recognized by Mozilla by default).
To access our software you may want to follow the procedure outlined below. This has to be done only once. We apologize for any confusion caused by this.
