Hi Elizer, Let me clarify the issue; I successfully set up squid with ssl bumping feature /man in the middle proxy/ against my home network. Everything works perfect. I see the access.log every https connection url. To check if it is really working, besides theaccess.log, I started sniffing the traffic on the proxy interface. And the issue begins from here. If I sniff traffic generated by Internet Explorer, I can decrypt the sniffed traffic via Wireshark. But in case in Firefox or Opera, I cannot decrypt the packets, even though I own the private key of the root CA(of course). What should be the problem?
