My kindle fire hd 7 has a nice browser but I wanted versatility while surfing the web or using applications in general . I found a website that houses tons of free android apk.apps. www.androiddrawer.com
Make sure to turn on " allow installation of third party apps " before you start downloading.
This process does not root the device; just a cool way to get apps like king soft office, chrome, google earth etc. Without voiding Amazon's 1 year warranty
Hope this helps!
