Mozilla officially launched Firefox 19 for Windows, Mac, Linux, and Android with lower CPU limits to support 15m more phones

Changes & Improvements:- 

• The improvements include a built-in PDF viewer on the desktop and theme support on Google’s mobile platform. All users of old Firefox versions can upgrade it automatically.  
• The biggest addition in this release is PDF.js, a JavaScript library intended to convert PDF files into HTML5. PDF.js loads and renders PDFs quickly directly in the browser, and because it uses standard HTML5 APIs, it can run on many platforms (PCs, tablets, and phones). 
• Firefox for Android is now available to phones with minimum requirements of 600MHz, 512MB, HVGA, including the LG Optimus One, T-Mobile myTouch 3G slide, HTC Wildfire S, and ZTE R750. 
• Debugger now supports pausing on exceptions and hiding non-enumerable properties. 
• There is now a Browser Debugger available for add-on and browser developers (experimental, set devtools.chrome.enabled to true).

Google said to release touch-screen laptop this year

Edging into Microsoft's touch screen territory, the Web giant is said to have developed its first touch-capable laptop to run on Chrome's operating system.

Chrome OS already includes a touch-screen keyboard, which means that it shouldn't be too difficult to add a touch-centric interface to the operating system, especially with Google's experience with Android. The company launched two Chromebooks from Acer and Samsung last year. It's unclear which hardware manufacturer Google might have partnered with for the possible upcoming touch screen laptop.

Having touched on a traditional laptop is a growing trend and could be commonplace in the near future -- as it is for any mobile device now.
