JellyBean Android browser remembers acct credentials

view story

http://androidforums.com – Hello All, I have the Galaxy Nexus and just recently updated the firmware via Verizon to Jellybean. The update went fine but after a couple of days, I ended up doing a factory phone reset just to give it a fresh start with Jellybean. So after the reset I enter my gmail acct. and everything's seems to be running normal. However now I noticed when I surf the web, I'm automatically signed in when browsing pages. The main google website has this "more" button on the upper right, and when you click on it it shows that you are signed in. -Is there anyways to keep it signed of (General)
