This means that the average web user won't have the DNT option just yet, but Google says that it will be rolling out by the end of this year.
Google spokesman Rob Shilkin told All Things D, "We undertook to honour an agreement on DNT that the industry reached with the White House early this year.
"To that end we're making this setting visible in our Chromium developer channel, so that it will be available in upcoming versions of Chrome by year's end."
The setting allows users to send an automatic request to every website that they don't want third-parties like advertisers to be able to track them as they journey across the internet and use that information to target adverts towards them.
The main problem with DNT, though, is that not all that many websites and advertisers actually abide by it, since it's more of a guideline than an actual rule.
Twitter supports it, for example, but Facebook does not. So even if you turn DNT on in your web browser of choice, advertisers could still be peeping at your efforts to find the perfect wardrobe on one site and advertising a bunch of cheap crappy wardrobes to you on another massively irrelevant site.
