Jackson, along with three colleagues from Stanford University, will present their findings later today at the Usenix Security Symposium in Washington, D.C.
Internet Explorer (IE), Firefox, Chrome and Safari offer private browsing intended to cloak a user from Web sites and erase all browsing evidence from the PC or Mac.
