Do-Not-Track in Chrome and Firefox: Different Approaches, Same Fatal Flaw

Google and Mozilla both wish to hand down you many privateness controls in their Web browsers, but the way Chrome and Firefox handle do-not-track are quite polar.

Google will, ironically, rely on tracking cookies to help users opt out of activity ads. The Keep My Opt Outs Chrome extension, which was proclaimed Monday, activates do-not-come after cookies from the Network Advertising Enterprisingness, telling them not to cut through your deportment on the vane.

Ad networks that enter in the NAI already allow you to opt out on the group's internet site, only these preferences are lost if you clear your browser's cookies. Keep My Opt Outs remembers your do-not-track preferences and adds new participants in the Network Publicizing First step automatically.

Mozilla wants to add an opt-out button to Firefox's basic settings, instead of using a browser extension. When users visit a website, Firefox will propagate the user's preferences every bit an HTTP header, effectively telling sites not to track users happening a case-by-case basis.

Firefox's feeler is dry cleaner on the drug user's end, but will take yearner to carry out. Even if Mozilla adds this feature in the adjacent version of Firefox–not a given, a Mozilla web log post on the matter suggests–websites will still have to recognize the HTTP header. For now, the cookie-based approach that Google is adopting will have to serve.

Still, both approaches share the same flaw: they rely happening the good faith of advertisers. Although the Network Publicizing Initiative consists of the 15 largest ad networks in the USA, unscrupulous advertisers in the entanglement's shadier corners certainly won't make up participating.

This speaks to a larger problem with the current hysteria o'er web trailing: telling pleasant websites not to follow your activity ultimately amounts to an approach on related advertising. Meanwhile, websites may run berserk with your info in more sobering ways. Just antepenultimate hebdomad, Facebook revealed that developers are free to gather home addresses and phone Book of Numbers from user profiles (Facebook has since tabled the plan while it thinks of a style to better warn users about liberal away their contact details.)

Personally, I'd rather see a banner ad for a television game based on my browsing habits than kick in away my phone number just for playing a game on Facebook, but there's nary browser extension to keep the latter.
