One in four don’t clean their stinky old browsers – especially Firefoxers

Nearly one in four netizens are using outdated web browsers and are therefore easy pickings for viruses and exploit-wielding crooks.

The average home user upgrades his or her browser to the latest version one month after it is released, according to a survey of 10 million punters. Two thirds of those using old browser software are simply stuck on the version prior to the latest release – the remaining third are using even older code.
