All sites I visit show a message, "Your connection is not secure," including Firefox.

Last night after updating my Bitdefender security and a reboot, I've been encountering a "Your connection is insecure" message on every page I visit, including Firefox (Mozilla.org). It seems a waste of time to add exceptions to 100s of sites. Any suggestions or fixes? I've been a Firefox user for many years and have never seen anything like this.

I also recently updated Firefox to the most recent version.

hi, you should never add exceptions in these circumstances but fix the underlying issues - most probably you'll have to disable the scanning of secure connections like described in How to troubleshoot security error codes on secure websites

I had this problem after installing the new firefox quantum, on Windows 10 x64 fall creators update. But my AV is Windows Defender, I don't have any security software scanning secure connections. I think this is the first time I installed firefox on this system. I have had this problem on and off in the past.
