A social service manifest is a JSON file that describes to the browser how to instantiate a service worker for a service provider. The manifest is installed through a web activation page located on the providers website, or from a directory service such as AMO. You can see an example of the manifest and activation on the github demo project.
Service discovery
Services are expected to promote their providers to their users either through their own website or through Mozilla Marketplace. You are expected to follow criteria we have for SocialAPI providers in Firefox.
Service activation
Activating your service from your website is available starting in Firefox 23.
A Service is described by a small JSON manifest. This manifest can be sent to the browser by creating and dispatching the ActivateSocialFeature DOM event. This event must be user initiated for the browser to accept the data. The target element of the event must have a data-service attribute containing the serialized manifest. Details of the manifest contents are below.
Once the user clicks the activate button, they will be presented with an installation panel to enable your provider. If they choose to enable your provider, they will then see an explanatory panel that highlights the new Social toolbarbutton as well as indicates how they may manage their social providers through the Add-ons Manager.
Here is an example of providing a button on your webpage to allow users to activate your provider:
<html>
<head>
<title>Demo Social Service</title>
</head>
<script>
var loc = location.href;
var baseurl = loc.substring(0,loc.lastIndexOf('/'));
var data = {
// currently required
"name": "Demo Social Service",
"iconURL": baseurl+"/firefox16.png",
"icon32URL": baseurl+"/firefox32.png",
"icon64URL": baseurl+"/firefox64.png",
// the URL of the contents for the share panel
"shareURL": baseurl+"/share.html?url=%{url}",
// icons should be 32x32 pixels
"markedIcon": baseurl+"/unchecked.jpg",
"unmarkedIcon": baseurl+"/checked.jpg",
// should be available for display purposes
"description": "A short paragraph about this provider",
"author": "Shane Caraveo, Mozilla",
"homepageURL": "https://github.com/mixedpuppy/socialapi-demo/",
// optional

}
function activate(node) {
var event = new CustomEvent("ActivateSocialFeature");
node.setAttribute("data-service", JSON.stringify(data));
node.dispatchEvent(event);
}
</script>
<body>
<button onclick="activate(this)" title="activate the demo provider">Activate The Demo Provider</button>
</body>
</html>
