ON/OFF & Tab Blocker

A simple and lightweight extension designed to save browser memory when you have multiple tabs open. It prevents tabs from loading automatically when you start your browser, reducing memory usage. Additionally, the Lazy Tab feature ensures that tabs only load when you select them.

This extension also helps conserve resources when opening multiple URLs using Ctrl + Left Click and prevents temporary blocks from websites by limiting excessive requests to the same domain.

🚀 Version 2.0: The "Total Rework" Update
ON/OFF & Tab Blocker has been completely rewritten from the ground up to offer more control, better performance, and a premium user experience.

🛡️ Enhanced Whitelist System (GOD MODE)

Quick Whitelist: Added a one-click button in the popup to instantly authorize the site you are currently visiting.
Smart Sub-resources: Whitelisted sites now load perfectly by automatically allowing all necessary background scripts, icons, and connections.

⚡ New "Tab-Specific" Internet Override
Selective Access: Want global internet OFF but need to check one specific site? Use the new "Access for current tab" toggle to grant temporary internet only to your active tab.
Origin-Aware Security: Unlike standard blockers, our new engine handles Service Workers and background fetches, ensuring complex sites like forums and web apps work smoothly while authorized.

⏸️ Advanced Tab Blocker
Lazy Loading 2.0: New tabs are put "on hold" with a beautiful professional landing page, preventing they from loading data and distracting you until you are ready.
