Other people login to their Gmail account using my profile, and aren't considerate enough to logout. Because both the Gmail account and Chrome profile are in sync, logging into their Gmail account also switches the Google Chrome profile to their Google Accounts profile.
When I next open the browser, I am presented with their synced bookmarks, settings, history etc.
I know it's trivial for me to logout from their account and login to mine, but it's become enough of an annoyance that I'd like to attack the problem at the source.
Ideally, when I next open the browser, I would like to see no trace of their activity -- the profile should be restored to mine, and I should be logged in to all Google services using my account.
How can I do this?
