hello, which security software are you using - does it have an option to scan ssl traffic? if so please try disabling this function once and see if firefox can establish an encrypted connection to gmail successfully afterwards.
Thanks, I am using Eset smart security, When I disable its protection and firewall the problem is not resolved and firefox reports the error too.

Thanks a lot.
Thanks for the tip. I followed the advice and it worked well.
I use linux and I haven't eset or any anti virus but I have this problem too.
