Summary & Key Takeaways ​

• Firefox 151 for Desktop now includes support for the Web Serial API.
• This API allows web applications to communicate directly with serial-connected hardware.
• Devices such as microcontrollers, 3D printers, and development boards are now accessible from the web.
• The integration removes the requirement for native software to interact with these devices.

Our Commentary ​

This is a big one for the web platform! Web Serial in Firefox means much broader adoption and less reliance on Chrome-only features for hardware interaction. I've always felt the web should be able to talk to more things, and this pushes that boundary. It's exciting to think about the possibilities for web-based device control.
