Adding pfSense web certificate into Google Chrome

[archedraft]

I have been trying to add my pfSense web certificate into Google Chrome so that I stop seeing the message attached as a picture below. Has anyone successfully accomplished this? If so, would you please list the steps on how it was accomplished?

If I remember right, you had to create a Certificate Authority cert and then install it as a Trusted Root CA via Settings - Show advanced settings - HTTPS/SSL - Manage Certificates - Trusted Root Certification Authorities - Import.  It's been awhile since I played with that.

I believe I have done that (and tired multiple ways) but Google keeps showing me that screen. Is it possible that I setup my Certificate Authority incorrectly?

Anything's possible.

But you can confirm that Google does not bother your anymore?

I played with transparent HTTPS proxy a few months ago but I'm not running it at the moment.  Yes, when I did go to HTTPS sites I didn't get any MitM warnings.
