Please remove autopopulate on gmail login and/or browser - log out does not work properly and i cannot switch to other accounts because of these assumptions

Hi - I have no idea why you would assume that once someone logs in with a gmail address, they would only ever want to use that gmail address ever again. 

Further, why, when I click on “help” and am directed to my browser, I am forced to use my work email address and cannot decouple these things. 

This is really poor, and potentially dangerous, user management policy.
