Advertisers have so far resisted some of the Do Not Track proposals advocated by privacy groups arguing they are technological solutions that could quickly be rendered obsolete by the fast-moving Internet economy. When Micosoft launched its Do Not Track default browser, advertisers said they would not honor it. Meanwhile, members of the World Wide Web Consortium's tracking group, represented by advertisers, privacy groups and other stakeholders, have been unable to reach consensus about a universal Do Not Track browser solution.
In Congress, where baseline privacy legislation has moved at a glacial pace, Mozilla's news gave Sen. Jay Rockefeller (D-W.Va.) more ammunition for his Do Not Track Online Act. Introduced earlier this year, the bill hasn't gotten much traction and only has one co-sponsor, Sen. Richard Blumenthal (D-Conn.).
"With major Web browsers now starting to provide privacy protections by default, it's even more important to give businesses the regulatory certainty they need and consumers the privacy protections they deserve," Rockefeller said in a statement. "I hope this will end the emerging back and forth so we can act quickly to pass new legislation."
