Firefox 4 will not include a 'do not track' privacy option to block targeted advertising, according to the web browser's maker Mozilla.

The Firefox 4 browser will not ship with what we envision is the end-to-end solution. We don't think any browser can today.
On Monday, an AFP report stated that Firefox 4, which is due for release in early 2011, would include a 'do not track' privacy option to foil behavioural advertising. Behavioural or targeted advertising products track a user's behaviour online, and serve ads based on the user's perceived interests.
However, Tristan Nitot, president of Mozilla Europe, told ZDNet UK on Thursday that Firefox 4 would not have the option, which is technologically difficult to implement.
"We have been investigating [the option], but so far we haven't found a way of combining a 'do not track' option with a good user experience," Nitot said.
Nitot said there is a good chance that web pages would not load properly if a user has the blocker enabled. The multiplicity of sites that track user behaviour, added to the number of ways users can be tracked, means that blocking user tracking can break web pages.
Firefox already allows users to block some forms of behavioural advertising, Nitot said. Firefox extensions including NoScript — a Flash, Java, and JavaScript blocker — and Adblock Plus can mitigate tracking. Users can also sign up to Taco, an opt-out list that advertisers voluntarily follow, Nitot added. These plug-ins will be also available with Firefox 4.
A Mozilla spokeswoman told ZDNet UK on Thursday that the privacy option was just one approach and not a 'comprehensive solution' for privacy on the web.
"We have been working with other organisations to discuss ways to design the right solution, and there is more work to do. Firefox 4 will not ship with what we envision is the end-to-end solution; we don't think any browser can today," the company said in a statement. "Mozilla has always believed that users should have control over their web experience, including who has access to information about them and on what terms."
The company said that there is no easy fix to online privacy, and that any product would need to be a "simple, verifiable and complete" way to give web users control.
"[Do not track] will need to work for the two billion people on the web today and will require collaboration across the entire ecosystem, from users to web developers and anyone interested in creating an open and participatory way for users to control their web experience," the spokeswoman added. "And once defined, we will ship that solution as part of Firefox."
The privacy mechanism has support from US regulators. On 1 December the FTC issued a report (PDF) supporting a 'do not track' option for site users.

Mozilla guess what? I'm not upgrading until you make such privacy options available as I'm sure others will follow suit we want privacy not more draconian technology.
Hi zydok,
While it would be good to see a comprehensive and simple answer to online privacy included as a default in all browsers, it simply isn't the case right now. Most major browser - including Firefox, Chrome etc - allow you to control whether or not cookies are accepted, allow you control on whether to share your location data and include a private browsing mode. Most also support 3rd party extensions/add-ons (ad block plus etc) too, which allow more control of what you share. Still, it would be nice for that all to be included in a more simple 'one-click' form for all browsers.
