  1. Thanks for the heads up, fortunately FF updated itself for me. Do you run the NoScript add-on? Seems prudent these days.
    Have a good one.

      Hey Mark,

      I can’t imagine surfing the Net without NoScript – I’m not a big fan of walking through minefields. LOL!

      As well, I run WOT, AdBlock Plus, KeyScrambler, and BetterPrivacy as part of my Firefox install. All of this is supplemented by the usual AV’s, Firewall, and most important GesWall an Internet isolator.

      Good to hear from you.

    Hi Bill. Really enjoy your web site. I did not know if you already know this, but WOT is closing down on Nov 16th. This was really a nice add on to the browser and I have not been using it too long. (Thawte.com). Thanks for all the advice, Dave Curtis.

      Hey Dave,

      There is some confusion here caused by Thawte Web of Trust * *digital email certificate program, which is undergoing some changes, effective November. WOT (Web of Trust) the Against Intuition Browser add-on is not one and the same, and is NOT being discontinued. So stick with WOT Dave.

      I appreciates you bringing this rumor to my attention.

      Safe Surfing,

    Thank you Bill. I am sorry I misunderstood this. This is exactly why we have your excellent web site. We will continue to use WOT. My family has learned so much from you. Thanks again, Sincerely, Dave Curtis.
