Mozilla unveils Firefox OS Simulator 3.0

Mozilla has formally released version 3.0 of its Firefox OS Simulator, a tool for developers to test apps for the Firefox operating system from their Windows, Mac, or Linux computers.

Mozilla unveiled a preview version of the Firefox simulator in mid-March, but has now made some updates and launched a more stable release.

Among the updates Mozilla added in the last month-and-a-half are a keyboard shortcut that allows for repackaging, reinstalling, or restarting a current app, "drastically improving workflow speed, especially for packaged apps," Mozilla said.

The company also promised a significantly reduced download size for the Firefox OS Simulator, as well as a faster start time. There are also much newer versions of Firefox OS and Gaia, as well as general bug fixes.

The updated simulator is available for download on Mozilla's website.

Firefox OS Simulator launched in November, and each new version includes features that target the most common and needed requests. Version 3.0 comes with push to device, a fairly self-explanatory function that allows developers to connect via USB a device supporting Firefox OS, then push apps installed on the Simulator directly to the connected machine.

The OS is expected to launch on commercial phones built by the likes of Alcatel, LG, and ZTE this summer in Brazil, Colombia, Hungary, Mexico, Poland, Serbia, Spain, and Venezuela.

Phones from Huawei will follow later, as will other country rollouts.

Mozilla dev phones went on sale last month and were quickly snapped up.
