Tab Session Manager

About

Tab Session Manager is the most reliable way to save and restore your browser sessions. Never lose a session again.

FEATURES:

- Save all windows and tabs as named sessions with one click
- Full-fidelity restore: tab URLs, order, pinned state, active tab, tab groups (title, color, collapsed state), and window position and state
- Auto-snapshots every 15 minutes — keeps the last 10 snapshots automatically. Skips unchanged captures so your storage stays lean.
- Session detail view: expand any session to see every window and tab with favicons, titles, and tab group badges
- Edit mode: rename windows, edit tab URLs and titles, add or remove tabs, reorder tabs, move tabs between windows, and remove duplicate tabs
- Restore any individual window from a saved session, or restore the whole thing
- Update/refresh: re-capture current browser state into an existing session without losing its name or ID
- Duplicate sessions with one click
- Export a single session or all sessions as JSON — your data is never locked in
- Import sessions from a JSON backup file — move sessions between devices or restore from a saved export
- Search sessions by name, tab title, or URL
- Trash with 7-day undo — deleted sessions are recoverable. Auto-purged after 7 days.
- Dark mode support that respects your system theme
- Smart auto-naming: sessions are automatically named after their top 3 domains
- Window labels: see the top domains in each window at a glance
- Letter-avatar favicons when a site has no favicon
- Confirmation before restoring large sessions (20+ tabs)

WHY IT'S DIFFERENT:

- Your data never leaves your device. No accounts, no cloud, no servers.
- No content scripts, no host permissions — we can't read your web pages. We only see URLs and titles.
- unlimitedStorage permission means Chrome won't silently delete your sessions when quota is full.
- Sessions are append-only — saving never overwrites or destroys existing sessions.
- Export anytime in open JSON format. Your data is yours.

PERMISSIONS:

- tabs: save and restore tab URLs and titles
- tabGroups: preserve tab group titles, colors, and collapsed state
- storage + unlimitedStorage: store sessions locally without quota loss
- alarms: schedule auto-snapshots
- favicon: show website icons in the session list

PRIVACY:
All data stays on your device. No analytics, no tracking, no servers. See our privacy policy at https://tab-session-manager.pages.dev/privacy for full details.
