Google Chrome has a simple user interface with a sophisticated core to enable the modern web . At it’s core is Webkit, an open-source rendering enginer - the same used by Safari. The browser in Android also uses Webkit. The browser also uses a multi-process architecture. Each tab within the browser runs independently, making the browser faster and more responsive. If one tab slows down or crashes, it doesn’t affect the others.
With the launch of Chrome a obvious issue arises , Google has been a prime Firefox promoter and distributer, and the source of its (comparative) wealth, so Google's focus on Chrome will inevitably diminish its support for Firefox. Whether Chrome will hurt Firefox more than it hurts IE or Safari remains to be seen.
However chrome is announced to be a opensource project , and also it does not force you to work with other google services ,as Larry page says "We don’t want to live in a world where things can’t be improved and that’s why Google is committed to the open-source platform with Chrome. "
