AMAZON SILK WEB BROWSER UPDATE
In order to download the new update for your Amazon tablet or phone you have to download the largest update. Amazon says the exclusive software can render pages faster than competitors, and save battery life in the process. Pages you view during a Private Browsing session do not remain in your browser’s history, cookie store, or search history after the session is over.” One of the key features in Amazons new tablet is a Web browser called Silk. Private Browsing is now available on our 2012, 2013, and 2014 Amazon Fire tablets as well as the Amazon Fire phone. For example, if you use Private Browsing while researching travel destinations for a surprise trip or shopping for presents, these sites will not show up in your browsing history when someone else uses your device. With Private Browsing, you can surf the web without saving a record of your visits. In a statement issued on the official Silk Blog the lead developer said “In response to customer feedback, we are excited to announce support for Private Browsing. Today, Amazon has announced that this critical feature is now available.

One feature that has sorely lacking is private browsing, so you can cut down on the footprint you leave online and avoid some of the cookies that tend to follow you around. The Amazon Silk Browser is fairly innovative because it can buffer in advance websites you visit on a regular basis, to cut down on the load times.
