List of all Tabs by CK

All your tabs in one list. Click the toolbar button for a popup, or open the sidebar — both show every open tab, one row each, with its favicon and title. Click a row to switch to that tab. The popup and the sidebar remember their own view and filter settings, so you can keep them set up differently.

Three views:

• all — every tab, in window order. Pinned tabs stay visible in an overlay on top while you scroll.
• recent — your tabs in the order you last used them, with age labels ("2min", "3h", "5d"). A tab restored with undo-close returns to its own place in the history instead of the top.
• dups — tabs that have the same URL open more than once, grouped, so you can close the copies.

Find-as-you-type search. Just start typing: matches are highlighted or the list is filtered down to them (your choice, per view). Multiple words narrow the search, a leading minus excludes ("mozilla -bugzilla"), and container names can be used as search terms. In single-window mode, matches from your other windows are appended under their own divider.

Stars. Star the tabs you keep coming back to and flip on the star filter to see only those. Stars survive undo-close and session restore.

Made for many windows. One click switches between "this window" and "all windows". Every window gets a stable color tag and can be named; searching, duplicates and recents work across all of them. Keyboard shortcuts can be assigned to jump straight to a specific window.

Manage, not just view. Close tabs from the list, unload (suspend) tabs to free memory, hide unloaded tabs, sort a window's tabs by title or site, and drag rows to rearrange tabs — including into other windows.

Fast at absurd tab counts. The list is virtualized and the whole pipeline is tuned for large sessions: it stays responsive with thousands of tabs open (tested with sessions with over 9,000 tabs).

Yours to style. Light and dark mode, two UI sizes, quick-settings right in the list header, and custom CSS for everything else.

Private. No data collection, no telemetry, no remote requests — the add-on never talks to any server. That is also declared in the manifest.

Based on the classic "All Tabs Helper" — continued and evolved in 2026. If you used ATH, you will recognize the layout and look.

Evolved from All Tabs Helper:

• Performance overhaul end to end: virtualized list rendering, cached tab data, coalesced updates — view switches and rebuilds that used to freeze with big sessions are now instant.
• New: starred tabs with a per-view star filter.
• New: multi-window toggle, per-window colors and names, cross-window search results, window-jump shortcuts.
• Recent view rebuilt: per-tab history that survives undo-close and session restore, with age labels and background-opened markers.
• View options (filter vs highlight, starred only, hide unloaded) are now remembered per view and separately for popup and sidebar.
• Quick-settings menu in the list itself — the important options without a trip to the options page.
• Many bug fixes, plus removal of legacy bulk/flag features and several permissions the add-on no longer needs.
