Foxconn Technology Group, best known as the go-to maker of Apple’s iPads and iPhones, said Monday it had embraced Mozilla’s Firefox OS and would use the mobile platform on a raft of new devices, including a tablet it showed off at Computex. The company also demoed several smartphones running the Firefox OS and said it would make tablets, laptops and other devices supporting it.

HP is reportedly working on a series of Android devices, the first of which could be a high-end tablet powered by Nvidia’s Tegra 4 processor. The move is a sensitive one for HP, which tried to crack the mobile market in 2010 by purchasing Palm for $1.2 billion, but saw that investment go down the drain.

The Mozilla Foundation on Tuesday announced that smartphones running its Firefox OS will be available to developers in February. The preview phones are being produced in collaboration with Geeksphone and Telefonica. The idea is to entice devs to create apps for the Firefox OS. “These devices have not been designed for consumers,” said Mozilla spokesperson Diane Zuniga.

Canonical this week announced Ubuntu for smartphones, a version of the Ubuntu Linux operating system aimed mainly at high-end superphones and entry-level basic smartphones. Ubuntu is compatible with a typical Android Board Support Package, said Canonical, which provides engineering, online and professional services to Ubuntu customers.
