    I have installed Fiddler, and made changes in Tools - Fiddler Options - HTTPs - checked "Capture HTTPs Connects" and "Decrypt HTTPs Traffic".

    While running the Fiddler, I am not able to access / open any websites in any browser IE / Chrome. Below is the error I am getting.

    Certificate Error: Navigation Blocked

    There is a problem with this website’s security certificate.
    The security certificate presented by this website is not secure.
    Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.

    If I close the Fiddler, I am able to open all the websites in IE / Chrome. Could you tell me how to resolve this issue.
