DNT+ or Sandbox ? Rated 1 out of 5 stars

Well, With Do Not Track Plus, all NAI's companies can store their own cookies. We don't like that.
Firefox does efficiently refuse third party cookies, when this option is set ON.
I have read all recent reviews and this add-on still does not convince me.
Finally I rather use the SANDBOX of Quick Heal Total Security 2013. So cookies are stored in a virtual environment.

This review is for a previous version of the add-on (2.2.9.520).  This user has a previous review of this add-on.

You seem to be confused...

...about how DNTMe works. DNTMe blocks tracking requests from ever taking place. It does not set NAI opt-out cookies. Perhaps you're thinking of TACO (Targeted Advertising Cookie Opt Out), which is an old product of ours?
