Does Do Not Track Plus work as advertised? Rated 1 out of 5 stars
Hmmm, It placed cookies on your computer which it claims are opt-out cookies. The thing with opt-out cookies like those are that they depends on the good wills of the websites that place those cookies in the first place. Firefox cookie option is a much stronger measure against tracking cookies. Be careful with this addon. My previous cricital post was deleted by this developer.This review is for a previous version of the add-on (126.96.36.1991).
Explaining what opt-out cookies are
Thanks for your feedback. As a side note, we don't have the ability to delete any user reviews, so there's no way that we removed it. It's possible that Mozilla removed your review because your were criticizing not DNT+, but the advertiser group (The Network Advertising Initiative or NAI) that distributes them. Generally, Mozilla tries to keep reviews focused on the software at hand, not external groups or actors.
You're also right to be wary about the good will of the NAI. However, we developed DNT+ to do as much as technologically possible (within the bounds of the law, of course) to stop tracking. That means we're using all sorts of methods, from the most aggressive--blocking tracking requests outright--to the more passive--broadcasting the Do Not Track HTTP header, which has no requirement that websites adhere to it. Despite some people's hesitance to trust advertisers, NAI opt-out cookies are a well-known method of privacy protection, and for our product to be the best it can be, we need to include them in it.
If you don't want to have DNT+ set these opt-out cookies, it's simple to adjust your settings. Just open DNT+, click on the "ad network" tab to expand it, and then click the link that says "turn off." Note that this will work in every browser *except* Safari at the moment.
A few other points:
First, everyone can do their own research on what opt-out cookies are: http://www.networkadvertising.org/managing/opt_out.asp. The opt-out cookies we set are Network Advertising Initiative (NAI) cookies. They aren't ours, and we can't access or see any of your data through them. We don't collect any of your information through DNT+, a fact you can verify yourself if you monitor the requests DNT+ makes to your machine. There's only 1 request per day for updates to our tracker-blocking rules. No personal data of any kind is transferred or collected.
We agree with some of the reviews that opt-out cookies are not the most effective and blocking is more effective, but opt-out cookies are simply an extra layer of protection. The pros outweigh the cons, which are pretty speculative. You can gain privacy from setting them, but you don't lose anything.
Thanks for sharing your concerns. I hope we've clarified things for you and that you'll consider changing your review.
