I removed the password and retype a new password for a new user account and register, this is the error i get:

Would you like to update the save password for "admin"?

I'm having the same problem in my FireFox and GoogleChrome.. How can i fixed this issue?? I believe is because when i login with my Admin account, i authorized Firefox and GoogleChrome to remember user and password for the website, and this is the error i got >.<

i've tried clearing History, Cache and Cookies... Same problem >.<

(Edited) The only working thing now is i have to remove my password manually from Firefox > tools > options > security > saved password

instead of doing this, is there anyway to prevent firefox/google chrome for asking "remember password" ?
