Mozilla announced the end of commercial development of Firefox OS in 2016 and to release the code as an open source project.
KaiOS Technologies picked up the source and used it as a central component for the company’s KaiOS operating system. The company had some success with the operating system as it is used on “more than 120 million devices” in “over 100 countries” according to KaiOS Technologies. KaiOS focuses on feature-phones, a market that Mozilla did not really entered when it worked on Firefox OS. Includes the KaiStore with over 400 apps such as Google Assistant, WhatsApp, YouTube, Facebook, and Google Maps.
KaiOS is based on HTML5 and other open web technologies and supports 3G/4G LTE, Wi-Fi, GPS, and NFC. Relatively old version of Mozilla’s Gecko engine; version 48, released in 2016 is still the base of the operating system. While the technology works fine for the most part, important features and developments such as TLS 1.3, WebAssembly, or Progressive Web Apps, are not supported by the current version.
The partnership will change that as Mozilla and KaiOS plan to introduce these new features in the mobile operating system. All changes will be released as open source according to the press release on the KaiOS website.
