# Release notes for version 1.22.3b

Zen Browser 1.22.3b adds [tab and folder search](<https://www.zen-browser.app/release-notes/1.22.3b>) to the command bar and updates to Firefox 156.0.1.

It also fixes a Windows system-handle leak, add-on installation in compact mode, and a bug on macOS 27 that made windows return to maximized after you restored them by double-clicking the title bar.
