Firefox 27 arrives with simultaneous Social API services, SPDY 3.1 and TLS 1.2 support, more languages on Android

Mozilla today officially launched Firefox 27 for Windows, Mac, Linux, and Android. Additions include Simultaneous Social API notifications, SPDY 3.1 support, and more languages on Android.

Firefox 27 has been released over on Firefox.com and all existing users should be able to upgrade to it automatically. As always, the Android version is trickling out slowly on Google Play.

Transport Layer Security (TLS) version 1.2 has been added to both desktop and mobile versions of Firefox. This is the latest release, although it was originally defined over five years ago in August 2008.

Desktop

Firefox 27 includes an update to the Social API that allows multiple social integration partners to send notifications at the same time. Previously, users could only see notifications from the social provider they had indicated in their Firefox toolbar.

The Social API first arrived in Firefox 17 back in November 2012. Mozilla developed the feature “to enable social services and providers to integrate directly into Firefox to make users browsing experience more social, customizable and personal.” In other words, the integration lets you keep up with the latest social happenings without having to switch between, or open new, tabs.

Since then, Mozilla added social partners Facebook, Cliqz, Mixi, MSN Now, and Weibo. Today, the company added two new providers: Delicious and Saavn.

The former lets you quickly share links to your Delicious network from wherever you are on the Web. The latter, a popular music player in India, lets you easily access top songs regionally, newest album releases, popular playlists, and the most popular radio stations.
