I'm trying to log onto a bank website. Firefox is blocking it. It claims an invalid certificate. I logged onto the website in question yesterday without a problem. I can log onto the website in question in Edge with a secure connection. What's going on? The website in question "centerstatebank.com."

I tried the link and got;

Your connection is not secure The owner of centerstatebank.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website. ++++++++++++++++++++++++++++++++++++++ There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
