Error code MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT how to access modem settings?

Trine

I am trying to access Zyxel VMG3625-T20A settings for the first time at https://192.168.1.1. but get the error: Connection is not secure and Firefox won't connect in that page.

Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

So what should I do now, please somebody help?

Other browsers said the same thing, but Opera asked if I want to continue anyway?

On my Firefox I can create an exception for that server.
