Firefox is a privacy focused web browser that doesn't track you. Brave is a privacy focused web browser that blocks ads and trackers although you can get the same effect by installing uBlock Origin on Firefox. Duckduckgo is a privacy focused search engine. Personally I recommend using Firefox with uBlock Origin installed and Duckduckgo as the search engine but if you don't like Firefox for whatever reason then Brave with Duckduckgo is pretty good two
