Mozilla’s Firefox OS will soon be making its debut on devices sold around the world, but until then Mozilla is still working to get developers crafting web apps that will run nicely on Firefox hardware. To that end, Mozilla has seen fit to provide developers with an early preview of its updated Firefox OS simulator and all the new functionality baked into it. Mozilla has been pushing out these simulators and updates since late last year , but the most notable change with this 3.0 release is that developers can now push existing work-in-progress applications to a connected Firefox OS device (assuming devs have one floating around). Other additions to the mix include the ability to simulate a rotated display as well as support for mucking around with the geolocation API to generate longitude and latitude values. In case you’re itching to start playing with things, you can download the 3.0 preview here — it installs simply as a Firefox extension, though only Linux users will be able to push apps to devices for the time being.
