# Note

If you haven't yet done so, you should really consider updating your browser to one that respects your privacy. Sadly, even foundations such as Mozilla started to display unacceptable behavior. As a fantastic replacement for firefox, chrome, safari, MS edge, etc, I strongly recommend brave. Now that DuckDuckGo has joined Google in actively indulging in censorship and propaganda, the quest for a reliable alternative search engine has become even harder. I currently have reservations about Qwant, so I am now using brave's search engine, which seems reasonable.
