I am happy to announce the release of version 2.0 of the Targeted Advertising Cookie Opt-out (TACO) Firefox add-on.
This version has been completely rewritten from scratch, primarily by Daniel Witte @ Mozilla Corp. It also includes opt-out cookies for 6 additional advertising companies: Snoobi, comScore VoiceFive, Hurra, Criteo, Coremetrics and EyeWonder.
A total rewrite
The original TACO was essentially a fork of Google's Advertising Cookie Opt Out Plugin. Google's original tool included one cookie -- I simply modified it to include an additional 100 or so opt out cookies.
The problem is that Google's original code wasn't all that good -- it would reload all of the opt-out cookies each time a new window/tab was opened, and then force them to be reloaded again every 10 minutes, even if none of the opt-out cookies had changed.
Perhaps this isn't such a big deal for a tool that is designed to install a single opt-out cookie. However, it clearly didn't scale well.
This new version is considerably faster, and no longer re-installs 100+ cookies into the browser each time a new tab/window is opened nor does it reinstall them again every 10 minutes after that.
Blocking third party cookies
One of the biggest complaint from TACO power-users was that the tool would not function when the user had configured the browser to block all 3rd party cookies (a suggested practice, and one which both Safari and Chrome do by default). I am happy to announce that TACO now plays nicely with blocked 3rd party cookies, and so the paranoid amongst you should feel free to go ahead and block them without having to worry about it breaking TACO.
A note about EyeWonder
Finally, blog-readers may remember that I recently pointed to EyeWonder's
After 9 days, it looks like the company finally
