Jetpack: A new generation of extensions for Firefox

The Mozilla people walk past highly active and now has presented a new project called Jetpack, which is to propose a new way to create extensions for Firefox.The idea is that if you are able to create a Web page can create an area without having advanced knowledge of programming.And you can end up being the final step to bring the extensions to many users who even know, or who use them are encouraged to create their own extensions and share them with others.demostrativo: As an introduction it is best to view the following video demonstration:

Jetpack for now is an extension, but that could be included in future versions of Firefox. One characteristic is that the extensions created using Jetpack not require restarting the browser, which many users would seem annoying and Mozilla is looking to solve a long time.

We will see a tutorial to install it (which we can then write about: jetpack) to see how we can begin to create an extension, with information on the API that is simple to use, and even a couple of examples: one, a kind of Gmail Notifier done in just 50 lines of code. In it you link you can see demos available with illustrative videos.

The idea is something intermediate between what is Greasemonkey extensions and we already know, but it was still powerful. All you need to know is HTML, CSS and Javascript. Even have JavaScript libraries like jQuery or the Twitter API and can add or create other libraries own.anyone can work with it and experiment a bit.
