I've been borrowing someone's laptop and am due to give it back. He only uses IE so I downloaded opera and chrome to keep things separate. All I've been doing is browsing but I've been on my email, twitter, google accounts etc.
Will deleting the browser's history & cookies and deleting these browsers be enough to get rid of my password details etc?
One reason I ask is he says he's never used opera, but when I went on it I could see his facebook and email accounts and I could log into them. (This is even after I'd deleted the browser & cookie history on IE, so I can't access them on there.) How does that happen? If at sometime in the future he downloads those browsers will my details pop up? I obviously don't want him to be able to log into my things.
