Firefox 151 Now Supports Web Serial API

Firefox 151 Integrates Web Serial API

Mozilla has rolled out support for the Web Serial API in the latest version of its Firefox browser, version 151, available on desktop platforms. This feature allows web applications to communicate directly with serial devices, such as microcontrollers and development boards, without the need for additional software.

Collaboration with Adafruit

According to recent reports, Mozilla collaborated with Adafruit, a well-known open-source hardware company, to test and refine the implementation. This partnership ensures compatibility with popular hardware like the Circuit Playground Express and other Adafruit products, enabling developers to create interactive web experiences that bridge the digital and physical worlds.

What This Means for Developers

With the Web Serial API, developers can now write web apps that read from and write to serial ports, opening up possibilities for IoT projects, robotics control, and data acquisition. The API is designed with security in mind, requiring user permission before any device access is granted, and is restricted to secure contexts (HTTPS).

Availability

Firefox 151 is available for download on Windows, macOS, and Linux. Users can update their browser to access the new feature. This move aligns with Mozilla's commitment to advancing web standards and providing developers with powerful tools for building innovative applications.
