Introduction to WebAPI

The Boot to Gecko project is based entirely on open standards and the source code is open and accessible to all. Where open standards are missing, we're working with standards bodies and other vendors to create them.

No longer need to learn anddevelop against platform-specific native APIs.

WHAT IS API??

The three levels of permission, in brief, are:

Web apps: These only have a basic level of permissions, and don't have access to privileged or internal APIs.

Privileged apps: These have all the permissions of web apps plus more. Hosted apps can't be privileged — they must be packaged apps.

Internal (certified) apps: These have all the permissions of privileged and web apps plus more. Certified/internal apps can only be installed on a device by Mozilla or a device vendor; not 3rd party developers.
