See the image below, how do I prevent that black box showing up and showing anyone who uses my device my sensitive data? How is this not a common setting to be changed? Very insecure and Horrible to have on by default. Recently switched to firefox from chrome because of security concerns but stuff like this is making me want to go back, because HOW IS THIS SAFE AND SECURE?!?!?!? I've typed in passwords in boxes that arent really password boxes, and firefox has suggested my own password in plain sight like in the image below. Strongly recommend firefox to not make this default and make it an accessible setting to disable because I've leaked my sensitive information to online calls because of this. This urgently needs to be addressed as a security concern. At least have a cogwheel button next to the black box to quickly disable this setting. Very very disappointed.
