theodp writes: The WSJ reports that a coalition of Internet giants including Google has agreed to support a do-not-track button to be embedded in most Web browsers — a move that the industry had been resisting for more than a year. The new do-not-track button isn't going to stop all Web tracking. The companies have agreed to stop using the data about people's Web browsing habits to customize ads, and have agreed not to use the data for employment, credit, health-care or insurance purposes. But the data can still be used for some purposes such as 'market research' and 'product development' and can still be obtained by law enforcement officers. Meanwhile, after Google got caught last week bypassing privacy settings on Safari, and was accused of also circumventing IE's P3P Privacy Protection feature, CBS MoneyWatch contacted Mozilla to see if it had noticed Google bypassing Firefox's privacy controls. After reports that Google ponied up close to a billion dollars to Mozilla to beat out a Microsoft bid, this seems to be one of those have-you-stopped-beating-your-wife type questions that has no good answer. Anyway, according to a statement attributed to Alex Fowler, global privacy and public policy lead for Mozilla: 'Our testing did not reveal any instances of Google bypassing user privacy settings.'
