The fine folks over at Amazon have further flushed out the firmware on its fiercely popular Fire tablet. Upgrading your Kindle Fire to version 6.2.2 will bring a handful of small performance tweaks, bugs fixes and, most notably, add a full-screen mode to the device's Silk browser. If you've gone ahead and rooted your Fire, applying the firmware bump will kill superuser access -- although a fresh build of BurritoRoot 2 should get you back on the straight and narrow. The new code is being pushed out over-the-air as we type, while those that enjoy the endorphin rush associated with instant gratification -- and know how to manually update a Kindle -- can find a link to the 6.2.2 firmware file below. Happy updating!
