I think Flash under Windows uses certificate authorities that are trusted by IE (Windows). If you have you own CA or using certificate signed by CACert.org, you need to import this CA certificate in IE as "Trusted Root Certification Authority". OK - i know that this is a problem for public servers to tell clients do this. But if you have corporate network there should be no problem to do this automatically. One more reason to push OS and browser developers to add CACert.org to trusted root authorities.
Hope this helps somebody:)

Flashplayer does'nt read the firefox certificates store, but the default CA certificates store located in the /etc/ssl/certs/ directory. You can add your own CA certificate with the following shell command: update-ca-certificates
Exemple (for Debian or Ubuntu users): (obviously, you need to be root) your organization is named 'myorg' and your CA certificate 'myorgCA.crt'
Create 'myorg' directory under /usr/share/ca-certificates Copy your CA certificate in the new created directory Edit /etc/ca-certificates.conf and add the following two lines (first line is for comemnt): # My organization CA myorg/myorgCA.crt
