Firefox OS is currently under heavy development; APC runs a PC-modified Preview release that is not a fully-functional end-user product at this time. Please read our list of known issues.
In order to drastically speed up the development of Firefox OS on APC we are giving away an APC for any development that can fix issues with the label Free APC in our GitHub repository.
If you’re interested, just send us a pull request. When validated, we will send you a free APC.
