## Description

**Tab Unloader** is a powerful Chrome extension designed to help you manage browser tabs efficiently by unloading inactive ones to free up system resources. This extension conserves memory and CPU usage, enhancing your overall browsing experience.

With the auto unload feature (disabled by default), you can customize when and how tabs are unloaded. Tab Unloader requires permissions to access tab URLs (to respect your whitelist), modify tab favicons before unloading for visual clarity, and read bookmarks—allowing you to open bookmarks in unloaded tabs seamlessly.

Optimize your browser's performance effortlessly with Tab Unloader's intuitive controls and settings.
