One of my favourite extension

I love this, I love my privacy and DuckDuckGo. The results are Good, and better than Any other search engines like Safe Guard Search. I'd use this anytime Over google. Than you, DuckDuckGo! For giving me my privacy back!

Al instalar privacy essentials, borra todos los buscadores alternativos. Al desinstalarlo, ya no se pueden restaurar, ni los demás, ni el propio Duck Duck go, que deja tambiñen de funcionar. Igualmente, interfiere con Firebox y deja de abrir os enlaces en nueva pestaña. Un auténtico desastre desde las últimas versiones.

The information this app provides is useful, but it keeps turning itself off and I have to re-enable it on every site I navigate to, rendering it fairly useless.

Changes your default search engine without first asking for permission to do so. Other than that provides privacy features that are mediocre. Nothing that cannot be found in other addons as well. Only extra thing it offers is to conveniently generate a disposable email address.

Keeps users safe. Allows you to do anonymous searches. Blocks trackers.
High quality, working, fast search engine.
