Release build - 1.18.5b (2026-02-06)

This update includes a new setting to allow users who didn't like the window sync feature but still want to sync their pinned tabs across windows in a workspace to do so. Make sure window sync is enabled in about:config for this feature to work.

New Features​

• Added 'Sync only pinned tabs in workspaces' option to the 'Tab Management' settings so that only pinned tabs will be synced across windows in a workspace. This is useful for users who want to keep their pinned tabs consistent across windows while allowing unpinned tabs to be different in each window.
• Updated to Firefox 147.0.3

Fixes​

• Fixed an issue when drag and dropping tabs from normal windows to blank windows
• Fixed an issue on Windows systems with a large number of fonts installed where parts of the UI (tabs, menus, and Settings) could display garbled characters or symbols instead of readable text.

Release build - 1.18.6b (2026-02-12)

New Features​

• Overflowing web extensions will now appear below the urlbar instead of being added back into the site control panel. This only happens in single-sidebar mode.
• Zen will now follow the XDG Base Directory Specification for storing its configuration and data files. This means that on Linux, configuration files will be stored in ~/.config/zen. Note that compatibility with the old configuration directory (~/.zen) will be enabled if the directory exists.
• Dragging a tab to the center of the window to create a split will now give the option to split on top or below.
• When typing directly an url or domain, a second search result will appear with the option to search for the url or domain on your selected search engine.
• Added a '--blank-window' command line argument to open a blank window without pinned tabs, spaces, etc.

Fixes​

• Zen will now restore unpinned tabs after a crash, even if the 'Restore previous session' setting is disabled.
• Fixed syncing bookmarks with your Mozilla account not working correctly.
• Other quality of life improvements and bug fixes.
