Mozilla pulls tracking trigger for Firefox 22, ignores ad industry attacks
Mozilla has added automatic third-party cookie-blocking to a preview version of Firefox 22, a move that will put the feature in most users hands by late June and the company on a collision course with the online ad industry.
Advertising trade groups have blasted the new cookie blocking, calling it "dangerous and highly disturbing," and promising that Firefox users would see more online ads as a result.
On Friday, the privacy advocate who created the blocking code said it had landed on the "Aurora" build channel. "The new Firefox cookie policy has migrated to Aurora!" tweeted Jonathan Mayer, a graduate student in computer science and law at Stanford University. Mayer is also one of two Stanford researchers who created the HTTP header implementation that signals a user's "No Dot Track" privacy preference.
