π‘οΈ Tab Shield & Saver
Protect active tabs from accidental closes and stash entire browser sessions with one click.
A lightweight Chrome extension for people who live in too many tabs. It keeps important pages from vanishing by accident β and parks a whole window of work when you need a clean slate.
No servers. No accounts. No tracking. Everything stays in your browser.
β¨ What it solves
Closing the wrong tab (or the whole window) is a tiny click with a big cost: lost research, a forgotten checkout, a half-written form. Tab Shield & Saver does two jobs:
- Shield β lock the current tab. If it gets closed, the service worker reopens it automatically. If the entire window disappears, the URL is saved to a local backup instead of being lost.
- Stash β save every restorable tab in the current window as a named session, then close them in one click. Restore later, inspect individual URLs, or delete what you no longer need.
π Features
- π‘οΈ Shield Mode β Protect the active tab. Accidental closes trigger an automatic reopen plus a desktop notification.
- πΎ Protected Links Backup β If a window is closed, protected URLs are stored locally. Restore them later from a banner in the popup.
- π¦ One-Click Stash β Park all tabs in the current window as a session (
title+url+ timestamp) and start fresh. - π Expandable Sessions β Inspect every saved link with favicons, open a single tab, or remove one URL with Γ.
- βοΈ Rename Sessions β Click a session title to give it a custom name. Stored in
chrome.storage.local. - ποΈ Safe Delete β Deleting a session asks for confirmation first.
- π Dark / Light Mode β Toggle in the header. Your theme preference persists across popup opens.
- π 100% local β Data never leaves your machine. Permissions used:
tabs,storage,activeTab,notifications.
