Tab Set History 作者： grad13

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.
