Firefox Prepares Additional 'Do Not Track' Options
Firefox 20 has barely made it out of the gate and Firefox 21 Beta is already in the channel for download and testing. The biggest change in 21 over 20 will be the new Do Not Track preferences and the Firefox Health Report.
"When DNT is off, it doesn't mean 'please track me.' It means that the user hasn't told the browser their choice yet," Lowenthal wrote. When you install Firefox for the first time, he said, the browser is set to neither so that the choice is entirely the user's.
