Rated 2 out of 5 stars
Taco 3.0 is not anything like Taco 2.0. This is less of an update and more of a new add-on.
As I said in an earlier review, if you are missing Taco 2.0, I forked it and keep it at http://jmhobbs.github.com/beef-taco or you can get the latest from Mozilla at https://addons.mozilla.org/en-US/firefox/addon/180650/
Don't be too hard on Abine, they are trying to build something innovative, and they really do care about your privacy.
