The game console's browser will be based on the NetFront Browser engine, which is the same engine powering the web browser for the 3DS.
It is compliant with HTML5 web standards, and earned a score of 323+8 from browser analysis site HTML5test.com. The site ranks web browsers on HTML5 usage on a scale out of 500 points, with up to 15 bonus points.
As a basis for comparison, the same site gave Internet Explorer 10 a score of 320+6, Firefox 16 a score of 372+10 and the latest version of Chrome scored 434+13.
Wii U's web browser will not be compatible with any plug-ins, including an inability to support Adobe Flash.
It also does not support the ability to save or upload videos or images through the web browser. The Wii U will support video and image sharing through specific games and online apps, such as New Super Mario Bros U's challenge mode; however, the web browser will not be one of them.
Additionally, since the Wii U gamepad only supports single-touch input, multitouch gestures such as pinch-to-zoom will not be supported.
Nintendo has said that it will hold a video conference before the Wii U's launch to further explain the system's online capabilities.
Wii U will launch on November 18 in North America, followed by a November 30 launch across Europe.
