The YUIConf folks have just posted their recording of a talk I gave there last year. I had planned to talk generally about the Firefox Marketplace, how it differs from other app stores, and how those differences create an overall apps ecosystem unlike other app ecosystems. All true, and all important.
I ended up giving a completely different talk. I decided I really wanted to show to use the Firefox developer tools to test, deploy, and debug an open web app running live on a Firefox OS phone. I had a lot of fun demoing live, including use of my patent pending cardboard and WebRTC ELMO replacement.
Take a look, I hope you enjoy it!
