Skype‘s browser application is now open for its users in the U.S. and the U.K., the company said on its blog and added that it will be rolling it out world wide in the coming weeks.  In November, Skype was beta testing the web application and had opened it up to a select number of users to make calls via a web plugin.

The web application is currently available on Internet Explorer 10 and above, the latest versions of Chrome and Firefox. For the Mac OS, Skype’s plugin supports Safari 6 and above. Contacts and conversations sync between the web plugin and the application installed. Skype for Web also has notifications for incoming instant messages, audio or video calls. The notifications pop up even if you’re using another app or viewing a different website in another browser window on mobile devices. Note, the company says that you’ll need to enable notifications when you sign-in.

Skype said that this is a move to enable real-time communications on the web. “We’re doing it because the hundreds of millions of people that visit every month told us they want to call and IM when they visit our website. We know how critical it is for you to get to your conversations – and Skype for Web helps you get connected anytime,” the blog read.

App for low bandwidths: Earlier in April, Skype said it is planning to roll out a new application specifically designed to operate in India’s low speed 2G and 3G networks and on mobile phones with limited processor speeds. The new application was the result of the company researching other companies’ VoIP products and found that services such as Viber performed better on Indian networks.

Other VoIP and communications platforms developments

– Earlier in April, Facebook has added a video calling feature in its Messenger app. The feature is currently limited to iOS and Android users in the US, UK, Mexico, Oman, Laos, Uruguay and some other European countries. Facebook mentions it will roll out the feature to other locations over the coming months.

– WhatsApp  introduced voice calling on iOS devices in April. The company had earlier rolled out voice calling on all Android devices. WhatsApp also has a web application of its own, though it still has no video or voice calling.

– Mobile messaging and calling application Viber came aboard the chrome operating system. Viber on the Chrome OS makes text, voice and video chats available to Chromebook, Chromebox users. Voice and video calls between Viber users are free, while calls to landline numbers have a fee.
