As well as launching a new update process and add-on synchronisation to their Firefox browser.
 Mozilla has also unveiled this week a new technology they have been 
developing that will enable websites to notify visitors that updates 
have been made to the site.
The new Mozilla API currently being developed works
 like this: The process starts with the Web 
site getting a URL where it 
can send notifications to the user. The URL points to the notification 
service, which is a secret between the user and the site. Then, the site
 sends a notification to the service. The service then delivers the 
message to the browser.
The
 new Push API notifications being developed by Mozilla are an easy way 
for websites to send small messages to users when the user is not 
visiting the site. Jeff Balogh explains:
“The notification API
 lives at navigator.notification. First we find the right API object and
 check that it exists. If it’s there we ask the user for permission to 
send notifications using notification.requestRemotePermission(), which 
returns an object we use to watch for events.
Once the notification is in the system, we’ll deliver it to the recipient on all the devices they have Firefox installed, but we’ll try not to show duplicate notifications on different devices.”
iOS
 and Android devices already currently support their own push 
notification services, but Mozilla are looking to make notifications 
available to the whole web. You scan find out more information over on 
the Jeff Balogh website.
