thank you, something on your system seems to be intercepting your secure connections by attempting to use a fake certificate (that's therefore not trusted by firefox).

next to the security software already in place, please run a scan with various other security tools like the free version of malwarebytes, adwcleaner & eset online one-time scanner. Troubleshoot Firefox issues caused by malware How to troubleshoot security error codes on secure websites

Hello Philipp,

          Moreover I am using Mcafee internet security. Does this have something to do with the error occured, sir?
more options

mcafee won't cause this. i suspect this is due to malware on your system or network that might not be detected by mcafee...
