Tab Harbor by HeathenAZ

Tab Harbor protects your browsing sessions by automatically backing up open Firefox windows, tabs, and native tab groups.

Choose automatic backup intervals of 1, 15, 30, or 60 minutes. Tab Harbor avoids creating unnecessary duplicate backups when your browsing session has not changed.

Features include:

• Automatic and manual named backups
• Native tab-group names, colors, order, and collapsed-state preservation
• Safe restoration into new windows
• Selective restoration of individual tabs
• Latest Recovery snapshot for unexpected browser closures
• Preservation of pinned, active, and muted tabs
• Light, dark, and system themes
• Configurable backup retention
• Protected backups that are not automatically deleted
• JSON import and export for transferring backups
• Toolbar backup-status indicator

All backups are stored locally in Firefox extension storage. Tab Harbor does not collect, transmit, sell, or share user data. Private browsing windows are excluded from backups.
