Overview
Rapidly reduce and organize your tabs
The Tabberwocky Tab Defenestrator is your stalwart ally against the chaos of too many tabs in too many windows. It’s a set of intuitive tools designed to help you quickly trim and organize tabs so you can get on with your day. The extension operates as a vertical tab list in your side panel, with real-time updates as tabs are opened, moved, or closed. Key Features: • Close Duplicates: see how many duplicate tabs are open, and close them all with a single click • Close by Domain: a grid of site icons displays the number of open tabs per site. Click the icon to close all the respective tabs at once • Merge Windows: Consolidate everything everywhere all at once into a single window • Sort Tabs: Organize tabs alphabetically by domain or in the order they were last accessed • Combined Actions: Single click to close duplicates + merge windows (customizable combinations on the roadmap) • Window View toggle: Switch the side panel view between your current window and all open windows • Tab Group integrity preserved during merges and sorts For a more detailed and interactive overview, please see tabberwocky.org/walkthrough. There's more on the roadmap, along with a separate Chrome extension providing complementary features. Accessibility: • Full keyboard navigation (arrow keys, Tab, Enter/Space) • Screen reader support with ARIA labels and announcements • Clear focus indicators, semantic structure, WCAG 2.1 AA standards Privacy: tabberwocky.org/privacy: • All processing stays local on your device • No tracking, analytics, or unexpected handling of data Questions or feedback: eric@tabberwocky.org Note: after the extension is installed, it will open the walkthrough page, https://tabberwocky.org/walkthrough Changelog V1.0.7 Refinements to toolbar button icon design and sizing v1.0.6: * Experimental feature -- hide URLs in sidepanel via ⌥U (mac) / Alt-U (windows) * Added ⌥D / Alt-D as default hotkey for Close Duplicates * Additional accessibility support -- screen readers can now name the number of duplicate tabs v1.0.4 & 1.0.5: Bug fixes and secondary UX enhancements v1.0.3: Distinguish Google docs, sheets, and other Drive files via ID rather than url v1.0.2: Additional scaffolding for high tab volume operations, along with UI refinements
