I find that the Norton Safe Search is invaluable as a researcher. I use many different search engines. Currently Norton Safe Search is only an option for Google, Bing and Yahoo. I would like to see this option apply to all search engines in the future.
F/U. Sorry I was referring to the Safe Web feature where an Icon is placed next to each web page on the search page, not the Norton Safe Search. It is an option only found on Google, Bing and Yahoo.
