2. Don't give your data to facebook
Why are you telling Meta your gender, your date of birth, or the city where you live ?
Facebook doesn't need to know any that. The more information they have about you, the more money they make. If you still use facebook, go to your profile right now. Delete these informations. It takes 30 seconds.
Remember to also visit Facebook privacy settings. So many don't do that.
It is designed to block invisible advertising trackers that gather data about you. But it also eliminates a significant number of ads. That makes browsing the internet significantly faster.
