  1. Its a seriously good and seriously smart add on but serves a big deal,always had issues running java on my system,slowed down the processing speed to a great extent,with this simple add on now and i can turn the java on when required and keep it turned off when not needed,helps in smooth functioning.Thank you for the post and the download link.Appreciated

  2. Great add-on thanks for the information.

    Sites that require silverlight are pretty rare and are usually big events where MS have bought silverlight usage (olympics, and major sporting events)

    I haven’t even installed silverlight on my PC but its great to know that I can disable/enable it so easily when I do

    Easily turning off flash and java is great for cutting the crp that appears on pages and slows down pageloads so I tend to leave them off till required

    This looks a very elegant way of achieving this Thankyou


  3. Just came across your site on Google. Thanks for the info. Just bookmarked ya :)
