All current versions of browsers improve user privacy protection. In recent testing, NSS Labs rated IE10 as being most secure in area of privacy controls.
QUOTE: You can buy dozens of security products designed to protect your online privacy in dozens of different ways. Really, though, when it comes down to it, shouldn’t privacy protection be built right into the browser? Truth to tell, the major browsers all have varying degrees of privacy protection built in, but some handle it better than others. A recent report from NSS Labs details the differences. For testing purposes, the researchers examined the latest versions of Internet Explorer, Firefox, Chrome, and Safari. They evaluated each product’s default settings, since the majority of users are unlikely to fiddle with the defaults. Internet Explorer emerged as a clear winner, which may come as a surprise to Chrome enthusiasts.
Conclusions – Internet Explorer provides the best privacy protection of the bunch, says this report. Safari, Firefox, and Chrome follow, in descending order. In its current form, Do Not Track is not effective; the report encourages readers to support legislation strengthening privacy rights.
