Mozilla has officially announced that their Firefox OS for mobile devices will be operating in 18 world markets and be the first Open Web Devices.

When Firefox OS takes off the first markets to get their hands on the Firefox OS devices will be Brazil, Colombia, Hungary, Mexico, Montenegro, Poland, Serbia, Spain and Venezuela. This is just the first wave of markets to roll out; additional markets will be announced at a later date.
