Zen Browser

A Firefox-based browser with a calm, focused UI.

Last updated: October 2026

About Zen Browser

Zen Browser takes the reliable, privacy-friendly engine of Firefox and wraps it in a beautiful, modern interface inspired by Arc. It brings features like vertical tabs, split views, and workspaces to the Gecko ecosystem, proving that you don't need Chromium to have a cutting-edge UI.

It focuses on "calmness" and ergonomics. The interface is designed to reduce visual noise and help you stay in the flow. It includes thoughtful touches like a sidebar for easy navigation and keyboard shortcuts that power users will appreciate.

As a relatively new project, it is still evolving, and you might find the occasional rough edge compared to a decade-old browser. However, for users who want the modern features of Arc but refuse to leave the privacy and independence of Firefox, Zen is the browser they have been waiting for.
