Since last Facebook update I've always had problems when logging in as always occur error messages! Now the Kindle system software has been updated with me recently. The problem with the sign seems to have been resolved, but now I have the problem that Facebook freezes now and then! Although I'll be back to the main menu, but to fix the problem with the freezing again on the Home button, I have the kindle restart, which I find very annoying. Here Amazon or Facebook should you urgently remedy !!!
