## Description

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.
