Features & Capabilities

Auto Tab Discard is a lightweight Chrome extension designed to enhance your browser's speed and efficiency by automatically discarding inactive tabs. It reduces memory usage by disabling JavaScript and DOM events on tabs that are not currently in use, helping conserve battery life on portable devices.

Key features include customizable options for discarding based on tab activity, exclusion lists for certain websites, preservation of tab states like scroll position and input content, and the ability to force discard specific hostnames. The extension supports pinned tabs, media playing tabs, and tabs with unsaved content, ensuring important tabs stay active. Additional plugins extend its functionality by enabling bulk discarding, timestamp storage for YouTube, and auto-discarding of new inactive tabs.

Unlike similar tools, Auto Tab Discard uses a native browser method to discard tabs, ensuring your sessions remain intact even if the extension is removed or the browser crashes. Overall, it effectively manages browser memory and battery consumption without sacrificing user experience.

Is Auto Tab Discard 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.

Auto Tab Discard requires a few sensitive permissions. Exercise caution before installing.
