Installing root certificate in Mozilla Firefox I followed this tutorial until the end at the end it says `copy everything beginning with the line: -----BEGIN CERTIFICATE----- and continuing through the line: ----END CERTIFICATE----- lines to a file named after the hostname of the server where the certificate will be installed.` Then I tried this with the just mentioned file I get `this is not a certificate authority certificate, so it can't be imported into the authority certificate list.` Could you please help ?

The tutorial help you create _Creating a Self-Signed Certificate_.

Firefox required the certificate to be signed by authorized authority.

In order to avoid the error you got, you can add the certificate as authorized authority.

Here you can find how to do it (with updates to up-to-date version of Firefox):

* Open Firefox
* Preferences
* Advanced
* Certificates
* View Certificate
* Authorities
* Import
* Provide the certificate
