cyborgninjaneer > Does DDG use Google ads? No. > Look into Qwant as another alternative. DDG is better than Qwant as Q was sold to an advertising company a while back. A SearX instance would be a good alternative. > Second question: Firefox is weakly sandboxed, but wouldn't GrapheneOS' hardening grant the application sandbox a bit of security-by-obscurity in terms of what could potentially break out of it? Different level of sandboxing. GOS will sandbox the application, Firefox will sandbox each tab (IIRC). You should look at using either Vandium OR Bromite (what I use). > Final question for now: If I use Tor browser specifically and exclusively for visiting .onion sites, what is the security implication if any Versus Tor browser for general use? Not much apart from being flagged as a Tor user.
