Tab3000 — Dimitar

Tab3000 is a keyboard-focused tab manager for Firefox that speeds up tab navigation through fuzzy search and batch operations.

Search & Filter: Type partial text to instantly filter tabs by title or URL. The fuzzy matching algorithm finds tabs even with non-contiguous characters (e.g., "ghpr" matches "GitHub Pull Requests").

Domain Grouping: Tabs are automatically organized by domain with collapsible groups and count indicators, making it easy to see how many tabs you have open per site.

Batch Operations: Use slash commands to perform actions on multiple tabs at once:

/close <query> - Close all matching tabs
/pin <query> - Pin matching tabs
/mute <query> - Mute matching tabs
Keyboard Navigation: Navigate with arrow keys, select tabs with Enter, and use Shift+Click for range selection or Ctrl+Click to toggle individual tabs. The default shortcut (Ctrl+Shift+Space) opens the popup instantly.

Container Support: Displays Firefox container badges, making it easy to identify tabs from different container contexts.

Lightweight & Fast: Built with Preact for minimal overhead and instant responsiveness. The popup opens immediately and search results update in real-time as you type.
