Recorder is not recording

Hi,
I am new to gatling and need some help in recording a session from a https page. May be, I am not setting the listening port and/or proxy correctly.

In mozilla, I set the following: HTTP proxy: 127.0.0.1 Port: 9043.
In gatling recorder, I set as follows:
Listening port: localhost HTTP/HTTPS: 9043 HTTPS mode: Provided Keystore
Keystore file: /tmp/truststore.jks Keystore password: ******** Keystore type: JKS

When I start the recorder and browse a https page, it does not record anything. Could someone please help me out what I am doing wrong?

Thanks.
