Zen Browser 1.22b has been released, featuring cross-device sync for Spaces, Folders, and active Tabs, built on Firefox 155.0.1. The update includes a redesigned squircle UI, a new onboarding process, and significant performance improvements, such as faster Space creation animations. Additionally, the update addresses 42 security vulnerabilities from Mozilla's advisory and resolves various issues, including live folders for GitHub and background audio drops on Linux and Windows. While Zen continues to improve and close the gap with competitors like Arc, it still lacks comprehensive sync features for passwords and cookies, which may limit its appeal as a primary browser
Zen Browser 1.22b Ships Cross-Device Workspace Sync, Squircle UI, and Firefox 155 Security Patches
Zen Browser 1.22b is live and built on Firefox 155.0.1, finally bringing cross-device sync for Spaces, Folders, and active Tabs via Mozilla accounts. The update wraps these changes in a redesigned squircle chrome, a fresh onboarding flow, and noticeably faster Space creation animations. Beyond the UI tweaks, the team patched 42 upstream vulnerabilities from Mozilla's latest advisory, fixed live folders for GitHub, and resolved background audio drops on Linux and Windows. Following a near-weekly release cadence all summer, the small open-source team continues to close the gap with competitors like Arc while sticking to its "calmer internet" philosophy.
