Firefox browser doesn't do like Chrome autologin setups does. As long as you have "remember" set you have to click the correct login and password to login. And Firefox will logout if you close the browser but Chrome does thing different but that is Chrome.

I use both all the time and this is not the normal behavior for Firefox, usually if the website is in my saved password list it will auto populate the username and password fields but I still have to hit the login button. Only when using Firefox and going to google login page do I have this problem where it auto populates the fields and selects the login without me doing anything.

And Firefox will logout if you close the browser

Perhaps because your own Firefox browser is set to [v] Delete cookies and site data when Firefox is closed in Settings.

The problem is not that it logs out when I close the browser, its that it auto logs in as soon as I go to the sign in page and I can't even choose which email to sign in with. I don't know if the link will work on here but this Dropbox link is a video of the problem.

If you watch my mouse it is not selecting the username(email)
