## Description

SuperStop is a lightweight Chrome extension that empowers users to quickly stop active background processes on webpages. It adds a convenient Shift+Esc keyboard shortcut and a toolbar button to instantly halt ongoing WebSocket connections, JavaScript timers, XMLHttpRequests, and any animations including images and videos. This functionality works independently of the browser's native Stop button, ensuring that users can regain control over resource-intensive or distracting page elements at any time.

Designed for improved browsing performance and user control, SuperStop's configurable shortcut makes it easy to address unwanted background activity with a single command. Whether you're trying to save bandwidth, reduce CPU usage, or just stop autoplaying content, SuperStop offers an effective and user-friendly solution.
