Hi, Thanks for your interest in Firefox OS. There are several ways you could use to try out Firefox OS. 1. You can try the Firefox OS simulator on your computer. See here for more: https://addons.mozilla.org/en-US/firefox/addon/firefox-os-simulator/ 2. You can install Firefox OS on an existing device. Please note that only some devices are supported and different devices have different levels of support. Tier 1 devices are better supported than Tier 2 or 3 devices. See here for more: https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Firefox_OS_build_prerequisites#Have_a_compatible_device_or_use_an_emulator If that doesn't work or you can't use the simulator, you can try getting a hold of Michelle Luna. She's Mozilla's Firefox OS Lead. You can [https://support.mozilla.org/en-US/user/463178 contact Michelle through PM] or by e-mail at mluna[at]mozilla[dot]com
