The Twilio Developer Contest is currently open until July 25th, 11:59pm PST, where developers are challenged to create Firefox extensions that utilize the Twilio APIs. To participate, developers can use Mozilla Labs Jetpack or Builder, and can find inspiration by leaving a comment on the page or joining a conversation in the forums. The contest allows developers to submit multiple extensions but can only win one prize, with the first place winner receiving a netbook and $100 in Twilio developer credit.
