Zen Browser

A beautiful privacy browser on Firefox

Overview

Zen Browser uses the Firefox Gecko engine with a modern Arc-inspired UI: vertical tabs, workspaces, and split view reflect current browser UX trends while staying Chromium-free.

uBlock Origin is bundled alongside Firefox privacy features (ETP, etc.). No Google Sync/Sign-in; Firefox Account Sync is supported. A fresh option if you want modern design without leaving Gecko.

Released in 2024, long-term stability is still unproven, but active development and community interest make it worth watching for Firefox users who do not want to lose a modern interface.
