## Description

**WebBT** adds Web Bluetooth support to Firefox on Windows, macOS, and Linux, allowing compatible websites to connect with nearby Bluetooth Low Energy devices. Most Web Bluetooth-enabled sites should work automatically after installing the extension and the required **WebBT Server** native application.

WebBT supports Firefox 128 and newer. Windows 10 version 1703 or later and macOS 10.15 or later are supported, while Linux support is experimental due to potential BlueZ connection reliability issues. Features and API availability may vary by operating system. Troubleshooting guidance, compatibility details, installation, and uninstallation instructions are available on the project’s GitHub page.
