All of my 300+ browser tabs are beautiful

October 14, 2026

I am a habitual tab hoarder so I created a Firefox addon to help me manage every one of my very special browser tabs.

Screenshot of List All Tabs (light mode) showing 306 open tabs (137 active and 169 unloaded)

Sort tabs by oldest, unload them, find duplicates, and consolidate tabs to a single window — buncha useful stuff in there!

Features

  • Go directly to a tab by clicking on it.
  • Shows Duplicate tabs open more than once.
  • Supports Multi-account containers for a tab (and the color of the container too)
  • Filter tabs by title, URL or container name.
  • Sort tabs by tab order, least recently used or most recently used.
  • You can unload tabs to free memory, either one at a time or with “Unload all” for all tabs or by host (YouTube tabs especially).
  • Show unloaded and Show pinned toggles.
  • Consolidate moves all of a host’s tabs into a new window.
  • Expand all and Collapse all for the Top hosts list.
  • Tabs you haven’t used for a week or more show a stale time difference (e.g. 2w or 3mo).
  • Light and dark modes.
  • Pinned tabs are listed last (and are not operable).
  • about:blank tabs are ignored.
