Firefox disconnects websockets connection for a self signed certificate

Question

I am trying to make websocket connection to a backend server that uses a self-signed certificate. In firefox I\'ve added an exception for the self-signed cert.

Answer 1

Firefox works with secure websockets (wss://) only when the certificate of the site is trusted.

With a self-signed certificate I was able to browse the site by adding an exception to the certificate. The exception is not used for websockets and the connection was dropped during the ssl handshake.

Instead I created my own Root CA cert and then another signed cert for the webserver. In Options > View Certificates > Authorities I imported the Root cert. Now firefox is able to connect over secure websockets without any issue.

Firefox does not allow for importing of self-signed certs as Authorities. Windows Certificate manager allows importing of self signed certs into the "Trusted Root Certificate Authorities" list.
