Tab Session Manager

Saves and restores browser sessions — windows, tabs, and tab groups.

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.
