Since a while I get the message (in German) "Firefox tries to enter "it2b.anyprox.de" Bitdefender is blocking this. What is behind?

I am using Firefox Version 73.0.1 (64-Bit) based on Win 10 (updated) on an Surface Pro (6th gen) Since a while I get the message (in German) "Firefox tries to enter "it2b.anyprox.de" with an invalid certificate. Bitdefender is blocking this. Can anybody explain to me, what is running here? Should I change something or simply ignore the message?

Firefox would warn you about an expired cert regardless, it doesn't need a 3rd-party anti-virus software for that. Wrt the warning, see https://support.mozilla.org/en-US/kb/troubleshoot-time-errors-secure-websites and https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean

Whether it's a good idea to let Bitdefender act as a man-in-the-middle and intercept your secure connection to the server is something you'll have to decide about yourself. https://support.mozilla.org/en-US/kb/error-codes-secure-websites
