Why Chrome Extensions Matter

Chrome extensions are lightweight browser applications that add new functionality to Google Chrome. They allow users to customize browsing experiences, automate workflows, improve security, and integrate productivity tools directly into the browser.

Instead of switching between desktop applications and browser tabs, extensions bring useful tools directly into the environment where users already spend most of their time.
