Mozilla wrestles with Firefox 3.0 security moves
Mozilla Corp. is still wrestling with adding a security feature to Firefox that its browser rival, Microsoft Corp.'s Internet Explorer 7, uses on Windows Vista to keep malware from hijacking computers.
In Vista, IE7 uses a technique Microsoft calls Protected Mode -- another name for "low rights" -- that blocks disk access to all but a temporary-files folder. The idea is that if an exploit -- a drive-by download, for instance -- attacks IE7 through a browser vulnerability, it can't install code on the PC's drive.
Last October, after Firefox developers had spent several days at Microsoft's Redmond, Wash., headquarters with the Vista team, a Mozilla engineer said they had come away with thoughts on how Firefox might take advantage of Vista's low-rights features. "We spent a while talking to members of both the UAC team and the IE team about ideas on how to structure our app for the lowest permission level," Vladimir Vukićević wrote at the time in a blog entry.
