Don't blink. If you do, you might miss your Amazon Kindle Fire updating to software Version 6.2. Amazon's not really saying what's new in the update other than "provides improvements to the operation of your Kindle Fire." But know that it does break root, so you'll have to jump through that hoop again (which you should be more than willing to do if you did it once already.)
The update's available over Wifi, or you can download it directly from Amazon, move it to your Kindle Fire yourself (just plug it in and drag the file onto it in your favorite file explorer), and go into the device settings and hit "Update your Kinde." It'll reboot a couple times, then all is well.
