With the release of Firefox 151, Mozilla has closed a years-long gap in browser capability, granting web applications the ability to speak directly to physical hardware through the Web Serial API. In partnership with Adafruit — a company that has long served as a bridge between digital tools and tangible electronics — Mozilla signals its renewed commitment to the maker and IoT communities. This is not a revolution in how we browse, but a quiet removal of friction: the kind of progress that matters most to those who have been working around its absence.
