BroadcastChannel API in Firefox 38 – Mozilla Hacks - the Web developer blog

Introducing the JavaScript Internationalization API – Mozilla Hacks - the Web developer blog
Firefox 29 issued half a year ago, so this post is long overdue. Nevertheless I wanted to pause for a second to discuss the Internationalization API first shipped on desktop in that release (and passing all tests!).

Black Box Driven Development in JavaScript – Mozilla Hacks - the Web developer blog
Sooner or later every developer finds the beauty of the design patterns. Also, sooner or later the developer finds that most of the patterns are not applicable in their pure format. Very often we use variations. We change the well-known definitions to fit in our use cases. I know that we (the programmers) like buzzwords. Here is a new one – Black Box Driven Development or simply BBDD. I started ap

localForage: Offline Storage, Improved – Mozilla Hacks - the Web developer blog
Web apps have had offline capabilities like saving large data sets and binary files for some time. You can even do things like cache MP3 files. Browser technology can store data offline and plenty of it.
