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) 🎯 Tab Group Integrity: Groups are preserved during merges and sorts UX Controls • Window View Toggle: Switch the side panel view between your current window and all open windows • Display/Hide URLs: Toggle URL visibility in the side panel tab listings 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 • No access to your tab page content Note: at installation, you'll see a "this can read your browser history" notification. This is because the extension's features need to access real-time tab information such as the tab url, tab favicon, and the order of tabs in your browser window. The Tabberwocky Tab Defenestrator does *not* access your actual browser history -- it only knows about tabs that are currently open. (See tabberwocky.org/privacy for more details) Questions or feedback: eric@tabberwocky.org After installation, a tab will open to provide onboarding information for new users 📝 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 announce the number of duplicate tabs v1.0.4 & v1.0.5 - 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
