Tab Master - Tab Manager, Backup & Restore

Tab Master is a browser tool for tab management, backup and recovery. It helps you search, organize, save and restore your tabs. Tabs piling‑up and hard to locate? Afraid to close your browser after work? Back up all tabs in one‑click and restore your workspace whenever you need. With dozens of pages open, find what you want in 3 seconds without endless scrolling. Remove duplicate and long‑unused tabs with one click. ## Core Features ### 💾 Tab Backup & Recovery: Finally feel safe closing your browser after work You do not need to keep dozens of work‑related tabs open all the time. Use “Import / Export Tabs” to save tabs, tags, groups and defer‑for‑later lists into a file, then close your browser directly. Next day, import the backup file and restore your full working state in one click. Supports standard JSON for complete state restoration, human‑readable Markdown, and OneTab‑compatible format for migration from other extensions. Transfer your workspace across computers or browsers by importing your backup. You can also recover from unexpected browser shutdowns using existing backups. ### 🔎 Tab Search: Locate pages in 3 seconds even with 50+ tabs open Use the search box at the top of the sidebar. Type keywords to match tab titles, URLs and domain names in real‑time with highlighted matches. Results are split into three sections: Pinned / Open / Recently Closed. Enable “Recency‑first sorting” to keep frequently‑used tabs on top. Assign hotkeys to your 4 most‑used tabs. Press `Alt+Shift+1~4` for instant global switching. ### 🧹 Tab Clean‑up: One‑click removal for duplicates and stale tabs From the Organize menu, automatically detect duplicate tabs (identical URLs opened multiple times) and long‑unused tabs with configurable thresholds: 1 / 3 / 7 / 30 days. Preview and select tabs before closing. Keep your sidebar tidy and responsive even with massive tab counts. ### 🗂️ Domain grouping & custom tags: Group same‑site pages and label your tabs Tabs are automatically grouped by registered domain. Pages such as `github.com` and `console.github.com` are clustered together so dozens of same‑site tabs no longer scatter. Common sites show localized display names. Create up to 15 custom text tags (Work, To‑read, Important, Today‑todo etc.), drag‑reorder them, and filter tabs by clicking tag badges. ### 👁️ Four view modes: Tile, List, Icon, Tree - Tile: overview of all items - List: detailed metadata - Icon: space‑compact layout - Tree: visualize tab opening hierarchy Tree‑view infers parent‑child relationships and shows you which link spawned each tab. ### 🎯 Focus Mode: Stay distraction‑free Enable Focus Mode: keep only selected visible tabs, others fold into a “Hidden” group. New tabs automatically join your active focus session. Exit automatically when you close the last focused tab. ### ↩️ Recently Closed & Defer‑for‑Later Automatically preserve your last 50 closed tabs for one‑click restoration. Send tabs you do not need right now to the Defer‑for‑Later list, free up tab‑bar space and attach notes for later review. ### ⚠️ Status badges & close‑protection Detect 5 states: playing media, muted, recording, screen‑sharing, connected devices. Show warning confirmation before closing high‑risk tabs to prevent accidental loss. ### 🎨 Personalization themes Log‑in to redeem avatar frames, background images and solid‑color themes via points. ## All data stays local on your device Browsing history, tab titles & URLs, groups and custom tags never leave your computer and are never uploaded to remote servers.
