Mozilla called it a day with Firefox OS for mobile handsets back in 2015 and said it would test the waters for an IoT effort using some of the same technology (and it has). But that hasn’t spelled the complete end for the tech on mobile devices.

Quietly, a company called KaiOS, built on a fork of Firefox OS, launched a new version of the OS built specifically for feature phones, and today at MWC in Barcelona the company announced a new wave of milestones around the effort that includes access to apps from Facebook, Twitter and Google in the form of its Voice Assistant, Google Maps, and Google Search; as well as a list of handset makers who will be using the OS in their phones, including HMD/Nokia (which announced its 8110 yesterday), Bullitt, Doro and Micromax; and Qualcomm and Spreadtrum for processing on the inside.
