11/18   In firefox (OS X), how do I reset the alert for enter/leaving a
        (non)secure page and/or posting info over (non)secure channel?  I
        pressed return for defaults too quickly and then could not find them
        under preferences.
        \_ This has been here for two days and nobody took a shot at it.
           How strange.  Anyway, I don't know about OSX specifically, but
           you can type about:config and see all the configuration stuff.
