Alcatel One Touch Fire is the first Firefox phone (hands-on pictures)

BARCELONA, Spain--The Alcatel OneTouch Fire is the first phone that runs Mozilla's Firefox OS, a new operating system for budget phones. We got our hands on it at Mobile World Congress.

The menu uses a grid of round icons.

You can't miss the rear cover, which is clad in Firefox orange.

The 3.5-inch handset is as small as smartphones go these days.

It also comes in a white and pink design.

The orange trim runs around the sides of the One Touch Fire, as well.

Whichever color you prefer, there's no escaping the Firefox branding on the One Touch Fire's rear cover.

The One Touch Fire has a single physical control below the display.

Up top are the power control and headset jack.

You won't find any exterior controls on the right spine.

On the rear side are a speaker and and the camera lens.

And there's nothing on the One Touch Fire's bottom end, either.
