    Version 4.1.4

    Released Jun 7, 2026 - 786.19 KB
    Works with firefox 140.0 and later
    New features:

    Two-column popup layout (new default): The popup now shows options and the duplicate tabs list side by side. The layout can be changed back to single column in the Customization section.

    Grouped view: Click the group icon in the duplicate tabs footer to switch between flat and grouped views. In grouped view, duplicate tabs are organised by matching rule group, collapsed by default. Each group shows a count badge and a close button to close all tabs in the group at once. The view preference is saved and shared with the options page.

    Pause monitoring: A new option lets you temporarily pause duplicate detection without changing any settings.

    New locale: Brazilian Portuguese (thanks to Volenski).

    Bug fixes:
    • Badge not repainted after opening a new window, closing a window, detaching a tab, or auto-closing across windows
    • Duplicate about:newtab tabs not auto-closed in Firefox
    • Whitelist UI broken when multiple entries were present in the popup
    • Popup scrollbar layout shift in Firefox 131+
