How can i add which is run by 'Blah blah' on firefox address bar (Self signed SSL)

I need to add which is run by text on firefox. Is it possible using self signed certificate. what are the steps i need to perform to achieve this 开发者_开发知识库?

Eg:

That text only appears for Extended Validation certificates. Whether you can do that with a self-signed cert depends on whether you can get the browser to accept EV certs from your signing CA.
