ON/OFF & Tab Blocker

Toggle internet access and block new tabs from loading until selected.

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) Complete Whitelist Manager: New dedicated window to manage your essential domains.
