it does not work well while using firefox with duckduckgo as my default search engine it only shows the safety of the link which i clicked on not of the whole web page which i have opened so i am unable to know which website it safe which is unsafe.
SO FIX THIS ISSUE

it is not possible to add exceptions for sites and if you are allow to go to a blocked page anyway, he asks for each link again and cancels downloads from this page you have allowed, wooow, damn addon

it seems it blocks nearly each site which adult content

no exceptions possible, so removed, bye norton :P

I have used Norton Security on my devices since I got my first PC.
