Zen Browser has released version 1.23.2b, which addresses significant data-loss bugs and enhances its Library hub. The update resolves issues that caused unloaded tabs to disappear when dragged into new windows, incorrect download-blocking messages, and session backup naming errors affecting non-UTC timezones. Additionally, two minor features were introduced, allowing for easier access to the Library and customizable options within it. This release, built on Firefox 157.0.1, showcases the project's commitment to user experience and rapid response to reported issues, reflecting its open-source nature and small development team

Zen Browser 1.23.2b Fixes Real Data-Loss Bugs and Rides Firefox 157.0.1

Zen Browser released 1.23.2b today, a patch that polishes its new Library hub and repairs genuine data-integrity bugs. It stops unloaded tabs from vanishing when you drag them into a new window, restores accurate download-blocking messages, and fixes session-backup naming that broke outside UTC timezones. The fixes were reported on October 8 and closed within a day or two by creator Mauro V. (@mr-cheffy), highlighting the project's rapid, maintainer-driven pace. Built on Firefox 157.0.1, the patch inherits Mozilla's fixes from MFSA2026-97 and MFSA2026-104, and native builds for Linux, macOS, and Windows are now available.
