Mozilla is set to take its Firefox OS platform into Africa, announcing new operator partnerships to support the efforts.

Backing the launch will be Airtel Africa, MTN South Africa, and Millicom’s Tigo. The upcoming push will mean that Firefox OS will soon be available on five continents – with Africa alongside 25 existing markets in Europe, Latin America, Asia and Australia.

But so far it has not been revealed which markets will see devices and when, or which manufacturers will be providing terminals. ZTE and Alcatel OneTouch have been leading the way so far.

“The continued growth of Firefox OS holds great promise for enabling millions more people to access the mobile Web at an affordable cost, while helping to remove control points in today’s closed mobile ecosystems,” said Rick Fant, VP of planning and ecosystem at Mozilla.

At Mobile World Congress earlier this year the company announced a partnership with silicon vendor Spreadtrum, targeting “$25” devices.
