I’m sure you’re aware, but in firefox, when the two check boxes shown Here are checked, it phones that domain of Googles, that’s circled, and checks their list of bad sites. If one turns them off, or blocks them, then they don’t afford the protection they supposedly offer, the question is, does one truly require such protection, some maybe, I can only speak for myself. And I advice that no one allows me to speak for them, always know for yourself! The only way one can be sure!
