When I go to a website and click on the 1Password icon in the toolbar, it re-opens the previous 1Password div, and then overwrites it with the prompt for the master password. Sometimes (not very often) there is a pause long enough for whoever is browsing to read the site and username.
To log into one of my accounts, an attacker needs a username and a password. A username isn't halfway there, but it is a contribution. Please don't give it away.
