Features & Capabilities

Tab Set History keeps a timeline of your open tabs by recording every tab open, close, and navigation event.

How it works:

The extension silently tracks which tabs are open in the background
When the URL set changes (a tab is opened, closed, or navigated), a snapshot is recorded
Open the viewer from the toolbar icon to browse your tab history
Click "Open all" on any snapshot to restore that exact set of tabs

Features:

Automatic recording — no manual action needed
Timeline view grouped by date
One-click restore of any past tab set
Deduplication of noise (redirects, brief tab reloads)
Auto-refreshing viewer with sync timer
All data stored locally in IndexedDB — nothing leaves your browser

Privacy: This extension collects no data. All tab history is stored locally on your device and is never transmitted anywhere.

Is Tab Set History Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Set History requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Grants access to browser tabs, which can be used to track user browsing habits and history, presenting a privacy concern.

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.

Tab Set History may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
