Tab Harbor

Automatically backs up browser windows, tabs, and native tab groups for safe recovery.

Tab Harbor keeps your browser workspace safe by automatically backing up open windows, tabs, and native tab groups. Restore an entire browsing session after an accidental closure, browser restart, or workspace change—while preserving tab order, group names, group colors, collapsed states, pinned tabs, and muted tabs. FEATURES • Automatic backups every 1, 15, 30, or 60 minutes • Manual named and protected backups • Full-page Session Manager • Search, filter, sort, rename, duplicate, protect, and delete sessions • Restore complete sessions or select individual tabs • Preserve native tab groups and their settings • Dock a window by saving it before closing its unpinned tabs • Find and safely close duplicate tabs • Light, Dark, and Follow Browser/System themes • Import and export portable JSON backups • Automatic recovery checkpoint before every restoration • Resilient restoration that continues if an individual tab cannot be reopened PRIVACY Tab Harbor does not use analytics, advertising, tracking, remote code, or external services. Saved tab and session information remains in your browser’s local extension storage unless you manually export a JSON backup. Private and incognito windows are intentionally excluded.
