Rejection of certain websites

"Secure connection and security warning error pages in Firefox." I have read this article, but it does not really help. Since about Monday this week that i have been experiencing a 'lockout' from certain websites that i trust and regularly visit. How is it possible that you can override my own personal security options? This is occurring with Duckduckgo. Using Google allows access to the website. Using Brave presents no problems at all.

So i am going to move away from Firefox to Brave. I appreciate warnings but not lockout. You guys do not know the websites i have been visiting for decades and they are all legal and ethical.
