Tab Options - Open source 作者: bluepie

Detects duplicate tabs, asks before closing duplicate tabs and focuses the existing one. Export and import tabs

Tab Options is open source: https://github.com/aghontpi/Tab-Options & an ultra-lightweight (<20KB) tab‑management assistant that keeps Chrome/Firefox clutter‑free.
► Core features
• Instant Duplicate Detection – automatically finds and helps manage identical pages.
• One‑Click “Save for Later” & Reopen – easily park tabs you don’t need right now and bring them back anytime.
• Import & Export Tab Lists – back up or share your open and saved tabs as convenient HTML files.
• Bulk Tab Actions – save all open tabs, close duplicates, reopen all saved tabs, and delete all saved tabs with ease.
• Fullscreen View – open the extension in a dedicated new tab for a focused, distraction-free management experience.
• Live Counter Badge – see at a glance how many duplicates or open tabs you have.
• User-Friendly Interface – includes dark‑mode support and keyboard shortcuts for power users.
► How it works
Tab Options watches tab URLs (never page content) to spot exact duplicates.
When a duplicate appears, you can (1) switch to the original and close the new tab, or
(2) keep both tabs open.
► Privacy & data handling
• No personal data, browsing history, or form inputs ever leave your browser.
• All settings and saved‑tab lists are stored only in local stoage.
• The extension does not sell, share, or use data for advertising or analytics..
