If you value privacy, Brave Browser (https://brave.com/) is worth a good look. Though the focus of the browser is on developing a browser that provides a way to benefit both advertisers and the people who consume ads, it has some really important privacy features built in and it is fast. Some of these privacy features are the normal ones with a privacy-based browser such as not saving browser history or cookies, forced https and ad blocking, but the one important feature that makes it so significant is the ability to utilize TOR which is critical. Without TOR or some type of VPN, you can still easily be tracked via IP address and pattern recognition algorithms.
