If you trust the third-party security vendor unconditionally, you may use it, but it will defeat the purpose of “encrypted communication (data will be collected by the security vendor)” and cause unnecessary trouble. Mozilla recommends against using this (scan SSL/TLS) function because “it is similar to a ‘man-in-the-middle attack’,” a method of eavesdropping and tampering”.

What this type of functionality is doing is that the security software interrupts the encrypted communication between the server and the browser, and changes the route from the browser intermediate host server, so that the communication goes through the intermediate host. The cause appears to be a “third-party security software function that intervenes and scans SSL/TLS communications”.
