SSL websockets about websockify

[chromer]

I tried using a self signed cert self.pem but i get:
1: handler exception: [Errno 1] _ssl.c:1331: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
I used this command to generate certificate:
openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem (as mentioned in noVNC documentation)
what shd I do about it in Firefox this works in chrome.
I am using FF 11.0 Chrome 17.0.963.79 m on Windows XP. I am running the server on a debian box.
Please tell me the correct way to do this.
Here is the chrome output(it works in chrome):
SSL/TLS (wss://) WebSocket connection
Version hybi-13, base64: 'True'
Path: '/websockify'

Since it's self-signed you need to get firefox to accept the certificate. Unfortunately, unlike normal HTTPS, WebSockets connections don't give you the opportunity to accept self-signed certs so you have to use another mechanism. You can either import the cert directly, or browse to the Websocket port directly using https and accept it that way. I describe this a bit more in the Troubleshooting wiki page.

Chrome automatically accepts certificates for WebSocket whether they are valid or not. Neither behavior is particularly ideal. I tried to push firefox to allow WebSocket certs to be manually accepted. Perhaps if you file a bug and we get multiple voices calling for it they might do it.
