// EDITOR'S TAKE
zen-browser is the practical move because it is Firefox underneath, so extensions, containers and profiles carry over while you gain split views and workspaces. Ladybird is the only project here building a genuinely independent engine like Gecko, but it is still pre-alpha, and Brave or Helium mean accepting Chromium in exchange for privacy defaults.
