Features & Capabilities

TabNest - Tab Session Manager 🪺

Save & restore tab sessions with one click. Merge windows, close duplicates, and auto-save everything you had open.

A calm home for your tabs. Name a session, restore it later, merge scattered windows, and keep a live snapshot of what you were working on.

Stop losing a research trail every time you close the browser. TabNest turns “save → restore → tidy” into a one-click habit:

Sessions

Save current window — optional name, favicons, tab count (5 sessions free, 200 with Pro);
Restore — reopen everything in a new window;
Lazy-load restore (Pro) — restore big sessions without loading every page at once;
Rename or delete any time.

Quick cleanup (free)

Merge windows — bring every tab into this window;
Close duplicates — same URL kept once across all windows.

Auto-save (Pro)

TabNest snapshots open tabs as you browse;
Restore the last snapshot if a window disappears.

Backup & restore (Pro)

Export all sessions as JSON;
Import a backup to merge sessions on another machine.

Configurable

Language: follow system, English, or 中文;
Auto-save and lazy-load restore are Pro toggles.

Free & Pro

Core features are free: save / restore (5 sessions), merge windows, close duplicates;
Pro is a one-time purchase that permanently unlocks 200 sessions, auto-save, lazy-load restore, and backup / import — and supports ongoing development.

How to get started

After installing, open the toolbar panel, name the current window, and tap Save session. Restore it later in one click.

Please note

After installing, refresh tabs that were already open so the extension can run on those pages. Per browser rules, the extension may not work on browser internal pages (such as the New Tab page, Settings, or Downloads) or on the official store page. Open another website to test TabNest.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

TabNest - Tab Session Manager is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
