Features & Capabilities

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.

Abandoned software? Authors should disclose which versions of Firefox are supported in the add-on description.

Is SuperStop Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SuperStop requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

SuperStop has earned a fairly good reputation and likely can be trusted.
