Mozilla Adds Web Serial Support to Firefox 151 With Adafruit Hardware Collaboration

Mozilla has added support for the Web Serial API in Firefox on desktop with the release of Firefox 151 . The API enables the browser to communicate directly with hardware devices like microcontrollers, development boards, and other serial-connected equipment without needing additional software. This update brings Firefox closer to feature parity with Chromium-based browsers, which have supported Web Serial for several years.
