Hi AP777, thank you for sharing the certificate. When I decode it, it has this
Issuer CN = Adguard Personal CA,C = EN
which suggests a program named Adguard Personal is intercepting all of your browser requests in Firefox. If you trust that program to read all your browsing, please check their documentation on how to set up Firefox to work with their fake site certificates (fake certificates are needed for a "man in the middle" to read your browsing).

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

Dear jscher2000, I am really grateful for your efforts. I restarted the program suggested in your reply as well as the device and it worked. I am very much thankful to you.
