Currently there is that some websites work properly on other browsers such as Mozilla Firefox, Opera, however, lead to unpredictable behavior.

In addition, this new version is once again an extreme increase in speed and not only on dual-core devices, but also on the "slower" single-cores. Evident, particularly the increase in speed in automatic text adaptation, which now goes almost without delay.
Also new is the integration of many APIs of the operating systems (especially on Android), leading websites in HTML 5 is possible, even to sensors, such as the position sensor, and even access the camera. This allows developers and developers new possibilities for web applications.
