Interesting add-on. I compared it with other 8 similar anti-tracking add-ons, and PrivacyDefense seems to block lot of stuff. Also, it is weight-light and doesn't affect browser performance.
The problem is: 1) It is impossible to know what was blocked. It will be nice a log or dashboard detailing blocked items. 2) The data base is old (5/19/2016) and it doesn't update. Even the add-on itself has not been updated in 9 months. It will be nice updates.
Major upgrade here, prior version had some issues, looks like this new version fixed all of it. They went away from the "trial period" model (thank goodness) and now offer a free basic version and an optional upgrade to a premium level with more blockers. Glad to see the new version and the expansion to other browsers (Chrome). Here's to safer surfing w/o big brother watching!
Does not work at all period. The first day I installed this add-on It did NOT Work at ALL. I see some claim you must pay for this app for it to work correctly. I will not pay for any add-on that I can not take for a serious TEST DRIVE First. Uninstalled and reported to Firefox for Removal.
