Hello! I am a long time Kindle user and have just bought a new Fire in a smart shade of blue. I want to turn off all the irritating highlighting other people have made in my Kindle books (prefer to use my own judgement, thanks). I have searched high and low online for the way to do this. All the references I can find are to older devices where the menus have different names. I have also tried the Help section and tutorial on the device. Can anyone here help?
