Amazon has made some major UI changes with the latest Kindle firmware 5.13.7, the browser has finally moved out of experimental status and is now just called Web Browser.Amazon's official change log for Kindle software updates is useless as always and so there's no real technical information on what has changed with the browser but it does seem bit more responsive, So does other parts of Kindle.I read HN on my Kindle and JS rich sites like TechCrunch wouldn't load properly in the earlier Kindle experimental browser but loads great now (incl. Article mode).
