  21. I just want to mention I am all new to weblog and really loved you’re web page. Probably I’m likely to bookmark your blog . You amazingly have tremendous articles and reviews. Cheers for revealing your web site.

  22. This Connection is Untrusted

    You have asked Firefox to connect securely to, but we can’t confirm that your connection is secure.

    Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site’s identity can’t be verified.
    What Should I Do?

    If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn’t continue.

    This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate. uses an invalid security certificate.

    The certificate is not trusted because the issuer certificate has expired.

    (Error code: sec_error_expired_issuer_certificate)

    1. Dear Mr. Asad,

      As the Mozilla 38.0.1 is very older version so some security features are not updated. But this can be use only for DSC work, rather than you can choose other browsers. So ignore the error message and proceed further and once completed DSC work you can switch to other browser for other work.

      Thanks & Regards
