Focus Last Selected Tab :: Provides natural / MRU tab ordering + Options for Tab Flipping, New Tab Select, and New Tab Location
FLST Chrome Revive is a modern Chrome extension that implements Most Recently Used (MRU) tab ordering to provide natural tab navigation behavior. When you close a tab or use the tab flipping feature, the extension intelligently selects the most recently used tab instead of Chrome's default behavior of selecting the adjacent tab.
- 🔄 Smart Tab Flipping: Navigate between your most recently used tabs with
Alt+N - 📍 MRU Tab Ordering: Natural tab selection when closing tabs
- 🆕 New Tab Control: Choose where new tabs open and whether they become active
- 🔧 Configurable Options: Customize behavior through an intuitive options page
- ⚡ High Performance: Optimized with modern service worker architecture
- 🛡️ Minimal Permissions: Only requests essential storage permission
- 📱 Modern Design: Clean, responsive options interface

| Setting | Description | Default |
