Mozilla is posting daily desktop builds of its upcoming Firefox OS for smartphones that can be installed on any Mac, Windows, or Linux computer.

We’ve been culturally challenged to build up a interested community of testers, but limited to our distribution of builds due to legal contracts. However, the release engineering team was able to get Daily desktop builds created and published online for anyone to play with. Refer to Gaia/Hacking for setup instructions. If you’re a web developer, you can use these builds to create and test your webApp against. If you’re looking to help do some testing, these desktop builds will also give you an immediate opportunity to play with and help us write testplans and file bugs. We encourage anyone interested to give the desktop builds a spin (available on Mac, Windows, and Linux), and get involved with the project!
