Folloyu's extension for Chrome allows users to seamlessly continue their online session on a mobile device. This add-on adds a button to the browser that enables users to send the URL of the current session to their mobile device. With this feature, users can easily switch between devices without losing their progress or having to manually open the same webpage on their mobile device.

To use the extension, users need a QR code scanner on their mobile device. If they don't have one, they can download the Folloyu app from the Android Market or Apple App Store. The app allows users to scan the QR code and instantly open the webpage on their mobile device.
