I already have experience with this like I accidentally click the save password and at that time
If this happens, the easy way to do this is to change your password, but it would be better if you never save passwords on the browser.
You're right but, let consider the possibility of the the public computer to have some hardware keyloggers which can easily capture your password entry during the action time. Saving password on a browser looks childish and in responsible of such person, some browsers can stole personal data for some dubious purposes. We must be careful of the type of browser we use to browse some important site on the Web.
I will not use any public computer to browse because if the possibility of keyloggers.
Dude, this is a separate debate, currently I have said that saving passwords can be dangerous.
Kellogger monitors the entire keyboard and is an advance level attack.
