I'm not sure if this is a Firefox or Google problem, I'm guessing Firefox because it doesn't happen in Chrome.

Every time I try to login to google in Firefox it auto logs me into a specific account, I don't mean it is already logged in, I'm logged out and where the blank field is to enter your account username(email) the drop down pops up and shows all the gmail accounts and picks one on its own then procedes to the next page for the password on its own. It's like someone took control of the mouse and was doing it for me. Really pisses me off because I'm trying to login to a different account and it chooses the same one every time and I can't choose. If this is some kind of auto login feature please tell me how to turn it off.

I want to delete my Firefox account. But while trying to sign in it required a verification code sent to my email address. The problem is I don't have access to that email address (it has been deleted). So I can't receive the verification code. In that case how can I delete my account?

my fire-fox a/c is suspended all over my devices, the message I get is for security reason , I am sure that this is a mistake or there is something that I am not aware about specially that I am someone with no security issues to raise up such decision , may I know why or shall I switch to another browser , I have been using firefox for a very long time and this is annoying to me , Kindly extend a helping hand to the situation and let me know if there is a fox for that

Thanking you in advance H
