Tab Keeper - Chrome Extension

Latest Release: v1.0.18

📅 Released: June 18, 2026
🚀 Chrome Web Store: 🔄 Ready for Submission

✨ What's New in v1.0.18

Feature	Description
🐛 Duplicate Tab Fix	Eliminated primary tab duplication when timer ends
🎯 Exact URL Matching	Primary tabs use strict matching (no domain-level fallback)
✅ Smart Reopen Check	Verifies tab doesn't exist before auto-reopening
🔒 Stricter Safe Zone	Only exact/base URL matches count as primary (prevents false positives)

Bug Fixed: Previously, when the timer fired, the extension could create duplicate primary tabs due to:

• Domain-level URL matching fallback (matched any tab on same domain)
• No duplicate check before reopening closed tabs
• Race condition in tab switch detection

v1.0.18 fixes all three issues with exact matching and duplicate prevention.

📖 Overview

Tab Keeper keeps your important tabs alive and accessible. Perfect for kiosks, monitoring stations, and enterprise deployments where specific web apps need to stay open and logged in.

🎯 How It Works

┌─────────────────────────────────────────────────────────────┐
│  ⭐ PRIMARY TAB (Safe Zone)                                 │
│  └─ Timer stops here - your "home base"                    │
│                                                             │
│  🔹 SECONDARY TAB (Monitored)                               │
│  └─ Auto-reopens if closed, but timer still runs           │
│                                                             │
│  ⏰ SMART TIMER (1-60 min)                                  │
│  └─ Away from primary? Timer starts → Auto-switch back     │
│                                                             │
│  🔄 AUTO-REOPEN                                             │
│  └─ Closed a target tab? We reopen it automatically        │
│                                                             │
