DRulz Well said.

Thank you so much! Nortons Safe search is a good idea but the search engine is not developed enough for release to the masses! I own 2 websites, now approved by Norton but their search engines still cant find them. Very frustrating. What else is Safe Search not able to find?

You don't have to use Norton Safe Search. Firefox comes with many search engines. You can use any of them.
