Not Working Properly Rated 1 out of 5 stars

DNT (2.05 and 2.06) still does not or unable to block one google tracker at its news website. DNT reports that it has blocked google trackers at other sites except at google news website.

Google on google is an exception

Thanks. We have a rule set that updates conflicts and so that page has a conflict and so the rule updates it to allow because in this specific case, since you're ALREADY on google, they can track you anyway. This is a fairly technical issue, but we'd love to discuss it further with you. Please send us an email at techqs@abine.com
We'd also recommend you use DuckDuckGo for more private search.

Spyware and Unreliable Rated 1 out of 5 stars

Version 2.0.6 of DNT does not block one google tracker at its news website. I also found a bunch of cookies that cannot be deleted. The presence of these cookies seem to indicate that this add-on is unreliable.

This review is for a previous version of the add-on (2.0.6). 

Please read the info about OPT OUT COOKIES

Take a look at this:
http://www.networkadvertising.org/managing/opt_out.asp

Basically, the same advertising networks offer consumers a cookie that opts them out of that networks behavioral targeting
So DNT+ uses those IN ADDITION to blocking these advertisers tracking requests if we see them on any page.
So it's confusing because you'll see cookies on your computer from the SAME company names as we're blocking. The difference? They're "good" cookies that are opting you out.
