Fiddler default cert maker should limit certificate validity to 820 days

Otherwise, Chrome may reject the certificate with ERR_CERT_VALIDITY_TOO_LONG

    The setting value(s) must be typed in directly. Default values are not shown in the about:config tab.

    I'm actually missing those settings in QuickExec, though I am running the latest version of FIddler. Am I doing something wrong here?

    Workaround for End-Users until Telerik Fixes this:

    Run about:config in QuickExec to edit prefs.

    The fiddler.certmaker.ValidDays preference controls the validity length, which defaults to five years; however, fiddler.certmaker.GraceDays is 366 by default (meaning cert validity starts one year ago).
