The Social API is an architecture that makes it easier for web browsers to integrate with social media services, using standard web technologies as the API. Once a social service provider is implemented for Firefox, it becomes possible for the browser to integrate web resources from a service, in-chrome user controls and information related to that service. The following articles explain how to implement a social service provider.
The Social API supports specific vertical use cases centered around social interactions, but does not tightly constrain those use cases, allowing flexibility and creativity for 3rd parties. Specific features supported are notifications, share, bookmarking (or save-for-later), sidebars and communications (e.g. chat and video).
