Sprint has launched the Lumen Toolbar, a browser extension that thrusts on users a whole bunch of advertisements and sharing tools. Powered by Skyfire’s Horizon browser extension platform, and riding on top of the native browser on Sprint smartphones, the Lumen toolbar lets users discover content, apps, and share content; while business users get the opportunity to feature mobile advertising.

The Lumen Toolbar is currently available on Samsung Galaxy S 4 and is scheduled to arrive on other Android-powered smartphones throughout 2013.
