If you don't think Mozilla cares about your privacy anymore, yet you use Qwant, you're probably not going to want to hear that the two partnered up last month.
I've been using Startpage with positive results.
There's also hardened Firefox solutions.
I second Proton... I love 'em. I use them for email and VPN. I always have a hard time putting all my eggs in one basket though, and try to avoid using any one ecosystem for all my organization. For example, I use an offline app for my calendar, and a self-hosted home solution for file management.
Great to see another person giving the one finger salute to big tech. Not sure about your ideas on Apple respecting your privacy though - they haven't given me that impression but maybe I'm misinformed.
Thanks. I currently use hardened Firefox (Arkenfox) and yes I do use unlock.
