Zen Browser 1.24b, released on October 29, introduces a migration feature for users transitioning from the soon-to-be-defunct Arc browser, allowing the import of Spaces and Profiles from both Arc and its successor, Dia. The update enhances the "Boosts" customization tool, enabling users to share their per-site tweaks, and incorporates the Firefox 159 engine for improved performance. Zen's design, influenced by Arc, features familiar elements like vertical tabs and workspaces, while maintaining compatibility with ad blockers due to its Gecko-based architecture. Additionally, the release includes security updates and fixes for various platform-specific issues, solidifying Zen's position as a viable alternative for Arc users

Zen Browser 1.24b Adds Arc Migration, Shareable Boosts, and Firefox 159

Zen Browser 1.24b shipped on October 29, bringing a migration path for users displaced by the shutting down of Arc. The Firefox-based fork can now import Spaces and Profiles from both Arc and its AI-focused successor, Dia, cementing its reputation as a Gecko-based spiritual successor. The update also makes Boosts per-site customization shareable, pulls in the Firefox 159 engine, and adds small touches like Ctrl-and-hover "Paste & Search" and Library-based tab management. Because Zen runs on Gecko instead of Chromium, ad blockers like uBlock Origin work unrestricted, though DRM-protected streaming remains a recurring caveat.
