P3P User Agents
Browsers and other programs that implement the P3P standard for customers.
P3P in Mozilla - Mozilla.org
Mozilla is implementing P3P directly into the browser.
Privacy Bird - PrivacyBird.com
AT&T has created a plug-in for the Internet Explorer browser (Windows) to view P3P policies and compare them to your preferences. Sites that don't match send a warning. I really like that angry little bird.
PrivacyFox - mozdev.org
A Firefox extension that allows Firefox to read P3P policy files in a similar way to Privacy Bird (which is IE only).
