I'm wondering if it is possible that Firefox will cease providing a button to proceed to MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT site? My question arises from the following experience.

I connected to a website and the Firefox browser didn't recognize the certificate that the website provided. The following message then popped up: " Potential Security Risk Ahead. " and the user was provided a button to "Accept the Risk and Continue", adding this unsafe website into the exception site list. I think that this is quite insecure. Is it possible that in the future Firefox won't support the button to "Accept the Risk and Continue" to unsafe websites and cease supporting the exception site list to the user?
