Here is a list of the best privacy browsers of desktop. I also consider usability in this list (Note: this is my opinion so you may disagree with it):

  1. Librewolf (Great for privacy and security)
  2. Dot Browser (Great for elegance)
  3. Tor Browser (Great for privacy but lacks usability)
  4. Orion (Mac only and is only in Early Access)
  5. Mozilla Firefox (Great for quick updates and the latest features)
  6. SeaMonkey (Great for people who loved the netscape)
  7. Ungoogled Chromium (Best for chrome lovers)
  8. Brave (Best for crypto enthusiasts)
  9. Vivaldi (Best for tweaking)
  10. Lynx (Best for lovers of the old internet!)
