Stop moving from the password box to the username box
It is super annoying and can be a huge security issue when this happens. Literally every time I login to PayPal, the email username is auto set in the username box, I click on the password box, and type the password in, just to find that PayPal decided to auto move my selection to the username box again and made me type my password in full view. Like why ** bleep** does this happen. Why.
